I'm leaving tomorrow. I have a small carry on type luggage bag (with shoulder strap) that I have put a 12pk of soda and a 6 pack of water in. It's going to be pretty heavy if I have to wait in line for a long time to board the ship. I was wondering if it's safe to send something like this through checked luggage.. or could it burst open from all the throwing around that the checked luggage endures? So what's safer? check or carry?
