good idea Brian,
I also may leae shampoo at home and found there's a walmart 4 miles from the hotel near the Orlando Airport we'll be staying at the night before (and after) my July 29th cruise - so I plan to check into our room, have them get me a cab and go to walmart for some essentials - this way we can travel only with 2 carryons and my purse, without worrying much about 3 oz containers. Anything extra, I'll leave at the hotel before our flight home.
