When planning your trip — both the whole trip and the daily schedule — make sure to leave room for downtime, changing plans, and spontaneity:

- Make time for relaxation. For every 10 to 15 days of rigorous sightseeing, plan at least 2 days for doing little or nothing.

- Mentally prepare yourself for those inevitable changes in your plans. You never know when circumstances will cause you to miss a train, for example. Try to rethink your unlucky situation in order to make the most of your new circumstances.

- Be spontaneous. Take advantage of unexpected opportunities, such as daytrips or festivals, and don’t be scared to spend more or less time in a place after you get to know it.

Often, travelers who return to Europe for the second or third visit discover that they can see many sights outside of the major cities by renting cars and staying in villas. They can go hill-town-hopping and explore one tiny corner of Europe at a time, enabling them to travel at a leisurely pace away from the crowds and pressures of the big cities. But on your first visit, you may want to visit as many major cities and sights as possible, and nothing is wrong with that. The whirlwind tour is still the best way to sample all of Europe’s offerings during your first trip. You can get the “required” sights out of the way, so when you come back (and you will return), you can concentrate on lesser-known attractions or explore an area in depth.

Seeing it all without going nuts

The idea of planning a large-scale trip can seem overwhelming — so much history and culture, so little time! Here are six ways to maximize your time and still see as much as possible:

- Don’t duplicate types of sights. You know that many sights in Europe are unique and worth seeing in their own right. But let’s face it: Visit some royal palaces or famous Gothic cathedrals, and they all start to look the same. Pick one or two examples of each and move on.

- Stay centrally located. Use your limited time to see as much of Europe as you can, rather than taking days to travel to a peripheral corner, especially on your first trip. Think about skipping some of the more geographically remote countries, such as Scandinavia, Portugal, Spain, and especially Greece, because — unless you take advantage of no-frills airlines — traveling to them takes forever. See Parts III through V to help you choose destinations that keep this idea in mind.

- Select side trips prudently. I highly recommend daytrips because they ordinarily add variety. But pick your excursions wisely, and make sure these trips don’t take time away from the major city you’re visiting. If you’re in Florence for just one day, don’t plan to see Pisa, because you’ll end up seeing neither. Reserve a full day to see any destination that’s more than a city-bus ride away.

- Go your separate ways. If you plan six days in London to accommodate the sightseeing wishes of each member of the family, you’re wasting time unnecessarily. You don’t have to tour Europe as Siamese triplets. Your partner can spend a few more hours in the British Museum and your kids can take a tour out to Windsor Castle while you check out Shakespeare’s Globe Theatre. That way you all spend a single afternoon doing what otherwise would have taken one and a half days.

- Practice extreme time-saving techniques. No matter how pretty the countryside en route is, you can save a lot of precious vacation time by taking night trains between major cities so as not to use a whole day just getting from Point A to Point B, even though this may not be the most comfortable way to spend the night. Because you arrive at your destination so early, this strategy also allows you to visit a museum before the crowds arrive; you can always take a siesta later.

- Know that you’ll probably come back. Assume it. Europe still has a lot left to see, no matter how much you pack in. Europe will wait for you.

Staying sane on the museum trail

Europe has generated quite an output of history and art over the past millennium, and you may feel like you’ve seen it all by the time your vacation is over. These hints can help you get the most out of your visits to the great museums without overloading your brain:

- Plan to go to big museums twice. Spread the visit over several days, if you have the time and inclination, because some museums are just too big to get through in one day. Consider this strategy for the Louvre, Museo del Prado, Vatican Museums, British Museum, Uffizi, and the National Gallery (London).

- Split up. Nothing is as subjective as taste in art. You and your companions don’t have to stick together in museums and spend all your time looking at the same paintings. You can each go through at your own pace and peruse your own pleasures if you part ways at the front door and set a time to meet. This strategy also gives you and your companions some time apart. (Even the closest of friends and family can get on each other’s nerves.)

- Try out the audio tour. Audio tours in museums have become quite sophisticated. You no longer have to deal with those barely understandable cassette audio guides that make everyone go in a big group from one masterpiece to the next. Now, most audio tours are digital, and you go at your own pace. The exhibited works have numbers next to them, which you just punch into the wand’s keypad. It then gives you the facts and background of the work, artist, era, and so on. You can just press Stop when you want to and continue on to the next painting. That way, you get the lowdown on just the works that intrigue you.

- Do the guided-tour thing. Most museum tours are led by certified experts who explain the background and significance of the most important works and can answer all your questions.

- Do your homework. When you’ve informed yourself as to what you’re looking at, the art can be much more engaging and interesting. Whether you skim your guidebook for the information or take a class in art history before your trip, a little brushing up on European artists and movements can enrich any museum-going experience.

- Create your own story. Look for humorous details the artist included, and try imagining dialogue next to the figures on the canvas. Any large canvas of a courtly scene or a banquet usually features details like two servants getting frisky with each other in the background, or a monkey and dog eyeing each other warily under the table. Most people get a little punchy after too many hours spent soberly contemplating creative genius. Feel free to make up stories to go with the scenes.

- Keep the museum hours in mind. In the later hours, museums empty out, especially the big museums that may stay open until 7 or 8 p.m. In summer, some museums may stay open as late as 10 p.m. or even midnight. If you’re a fan of museum books and postcards and plan to stay until closing, check to see when the gift shop closes. Gift shops often close 30 minutes before the museum itself closes.

- Spend your time on the masterpieces. Even a moderate-size museum can overwhelm you if you don’t pace yourself. Don’t feel obligated to see it all. Many museums include a list of the masterpieces on their floor plans, and you can skip whole wings that you don’t feel like going through.

Dealing with cultural overload

The French writer Stendhal, while visiting Florence, was so overwhelmed by the aesthetic beauty of the Renaissance — and so exhausted by trying to see absolutely everything — that he collapsed. Stendhal’s case is an extreme one, perhaps, but he’s not the last one to break down from too much Europe.

Even if you don’t faint in the piazza, after a few days or weeks of fullsteam- ahead sightseeing, you may become irritable and tired, catch a cold, or just stop caring whether you see another Giotto fresco in that church. When the idea of visiting the Louvre makes you merely groan and want to take a nap, it’s time to recharge your mental batteries. Check out these hints for remedying traveler’s burnout:

- Just because something is famous, don’t feel obligated to do or see it. If you’re going to wear yourself out, do it on the stuff you like. Feel free to skip what doesn’t interest you and go see what really floats your boat.

- Pace yourself. Go a little bit at a time in soaking up the variety of Europe’s cultural offerings. Schedule rest periods. I say again what is worth repeating: Leave room to picnic, to breathe, and to stop and smell the cappuccino. Do not pack too much into either your trip itinerary or your daily sightseeing agenda.

- Put variety into your sightseeing. Visit a church, ruin, or park, or relax in a cafe in between sights. Don’t hit one big museum after another. Give other areas of your brain a workout for a while. Your whole trip doesn’t then blur into one large, colorful mirage of Gothic cathedrals and old masters from which your memory can’t distinguish where Prague left off and Paris began.

- Do the siesta thing. In Mediterranean countries, almost all businesses are closed in the early afternoon anyway, so why not do as the Europeans do: Take a nap! A nap in the middle of the day can do you a world of good, both physically and mentally. You can take a riposo along with the Italians, and you’ll not only appreciate the culture more, but also be able to finish the sightseeing in Florence that Stendhal started.

- Take a break when the sightseeing starts getting to you. Whatever it takes to bring your cultural appreciation back from the brink, do it. Take a day to get off the beaten path. Go shopping. Go to a soccer match. But stop trying to rack up sightseeing points. Sit down and write postcards. Chances are you’ll get psyched to get back on the sightseeing wagon after describing to your friends back home the once-in-a-lifetime experiences you’ve had.
