Our advice: think about everything you want to pack and then only take half of that. Travelers are responsible for carrying their luggage around the hotel and airports, so it's important that it's a manageable weight and size. Plus, you'll want to save room for some gifts and souvenirs to bring back!
Bathroom bag (shampoo, brush, soap, toothbrush, toothpaste, deodorant)
ID and passport (if necessary)
