We switched rooms at the Boardwalk villas last week (June 10th to be exact) as we didn't like the first room, and they were booked up. We packed up in the morning and the bellman took all our stuff and stored it till that evening. I packed up the groceries into separate bags of what was needing to be frozen (ice cream, etc...) and refrigerated. They have a large facility for that and it worked out well. If I had known we were going to move, I would have waited to grocery shop! But they were helpful there - I don't know if it's because it was a villa but I'd imagine at a regular resort you won't have so much food to stay cool anyway - I bet they would store it fine.
