Can you put wrapped gifts in your checked luggage? My mom's b-day will be during our Sept. trip and we have a few gifts to take for her. I'd like to wrap them ahead of time, if I can, so I don't have to do it there. (We're sharing a room.) I know you can't have them in your carry-on or they will be opened, but I wasn't sure about the checked luggage. Anybody know?
