Oh, as much as I feel for you cause I can't imagine being that close to my wedding date I'm also so jealous! This is what you've been waiting for! I think I'd be trying to tell myself to try and calm down because being stressed is just probably going to make me not enjoy my time as much. Just try to let things happen. If you're worried about things that still need to be done or just finished making a list always helps me settle down. If its written down you can stop worrying about forgetting about it. and the last consolation is that if something doesn't get done or if something goes wrong, it doesn't matter cause as long and you, FI and your paperwork are all set you don't need anything else (except for a bathing suit of course!!) Have a great time at your wedding and enjoy every second of your trip!!
