Is it imperative to know ahead of time where the ship is sailing out of? We're going to be on the 9/11 Wonder cruise, but we're travelling to Jekyll Island (off the southern coast of GA) tomorrow and I don't know if we'll have internet access at our hotel. Is there a phone number we can call? We have to leave our car at Port Canaveral no matter what, right? So I guess we just get there as early as we can and hope for the best?
