In Europe, you'll walk with your luggage more than you think--in airports, on taxis, in subways, on buses, up and down stairs and in the streets. So pack light. European travel expert Rick Steves recommends limiting your luggage to one 20-pound, carry-on bag or backpack. Rather than packing for the worst-case scenario, think about what you can live without.
Prior to your trip, ensure you are in shape and ready for all the walking that a European trip brings. While traveling, eat nutritiously, wash your hands often and get plenty of sleep.
While Europe is generally safe, it's important to try to blend in to the local culture. Respect local customs. To thwart would-be thieves, Let's Go travel guides recommends carrying as little cash as possible and never letting your passport and bags out of your sight.
Since most flights to Europe are overnight journeys, you will probably arrive in Europe in the early morning hours, but your body thinks it's midnight. Resist the urge to take a nap when you arrive at the hotel. Instead, go to bed somewhat early on the first night, and by the next morning, you should start to recover.
By choosing small hotels and bed and breakfasts, traveling off-season, avoiding touristy restaurants, and investing in museum passes, you will save money in Europe. Also, avoid purchasing a Eurail pass if you're not traveling a lot; point-to-point tickets are cheaper.
