This wasn't a Cruise, but a few years ago we went to Disney World for our 5th anniversary with my parents. We drove down from Pennsylvania, (which we did in a straight shot). We checked in at the Wilderness Lodge, went to the room and started unpacking. My wife asked me if I had seen the cosmetic bag! I told her the last time I saw it was on the bathroom counter at home. We looked around for it, and I told her we must have forgotten it, no big deal we can just go to the store and pick up the things we need. She than explained to me that her birth control pills were in the bag. Panic insued. We went to a few pharmacies, they would not give her any, we went to 2 clinic's, they also would not give her any without permission from her doctor, which being a saturday and not having his # was not going to happen. We went back to the WL still not knowing to do, (we had planned on bringing back a few suvenires, but not that kind). We took a chance and went up to the Guest Service desk at WL, and explained the situation. The woman said that is not something that is uncommon, she said, enjoy your day in the park and when you stop back for dinner there will be a package at the desk for you, which is exactly what happened. Never underestimate the ability the Disney CM's have at helping in any situation.
P.S. Sorry for the misspelled words, my spelling is horrible.
