Pack toothbrush, toothpaste, and dental floss. Don't forget hair styling tools and supplies. Bring along moisturizers, razors, and all of the medications you may need.
Don't forget credit and debt cards. Phone chargers. Travel adaptors. And something for your dirty clothes.
Don't forget to pack everything you need to stay connected (if you want). Think about your computer, books, paper, games, earbuds, and more.
