Hard-won, practical advice to help you have a smooth, good time on the road.

Here are some general recommendations to help you have a good time.
Booking early gets you better deals. Before you travel, learn about the culture, transportation, and sights of your destination.
Take only what you need and outfits that work multiple ways — you'll save time and energy. Dress in layers for all conditions.
Copy your passport, ID, and trip insurance, and keep the copies separate from the originals.
Drink plenty of water, especially when flying or somewhere hot. If tap water isn't safe, stick to bottled.
Learn a few basic words — a simple "hello" or "thank you" goes a long way. Check the local tipping customs.
Take the chance to sample new foods, but avoid street food and unprotected water to prevent stomach trouble.
Shift your bedtime a few days before you leave to ease jet lag. Stay active during the day and get sunlight to help your body adjust.
