You could bring a hard sided cooler with you and pack it with clothes etc as luggage, just watch the size and weight so you won't have to pay extra. Airline websites should have the measurements and weight. Then just fill up the cooler with the free ice from the resort. What we do is buy a cheap styrofome (SP?) cooler and stock it with the water, milk etc. The ice will normally last one day. I just refill it in the AM while I'm waiting for everyone else to get ready to go to the parks. Of course we rent a car so that is why we get the cheap cooler. If we didn't have the car, we would go with the hard sided cooler and just tape it shut with some duct tape. The TSA people will most likely open it up and then reseal it and remember to bring extra tape for the trip back. We've even found foam coolers outside of the rooms while housekeeping was cleaning up and just asked if we could have them
