Prepared with a positive attitude and solid information, you’ll thrive in Europe. [...] a healthy dose of skepticism and an eagle eye in crowded or isolated places will help you stay safe. Traveling on your own, you’ll be more approachable and likely to meet a montage of fun, temporary travel partners. If you’re shy, you might also consider an organized European tour, where you can relinquish trip-planning to a well-seasoned guide and enjoy a built-in circle of travel partners. Social-networking sites like Meetup.com make it easy to find groups of like-minded travelers and locals. Make them an excuse to invite someone to join you for, say, a rijsttafel (rice table) dinner in the Netherlands, a smorgasbord in Scandinavia, fondue in Switzerland, a paella feast in Spain, or a spaghetti feed in an Italian trattoria. At restaurants, practice your verbal skills with your server (when I asked a French waiter if he had kids, he proudly showed me a picture of his twin girls). Plan your next day, study your guidebook or scrawl a few postcards to the folks back home. If bars and nightclubs don’t appeal to you as a solo traveler, enjoy the floodlit magic of European nightlife from a different angle. Go for a walk with gelato in hand and enjoy the parade of people, busy shops and illuminated monuments. Take advantage of the wealth of evening entertainment: concerts, movies, puppet shows, folk dancing.
