That was what I wondered, too. I haven't ever stayed at the resorts, but man, the bed on the cruise ship was possibly the most comfortable one I've ever slept on. I'd buy it in a heartbeat - if I know for sure that it's the same one.
To make it even more confusing, they carry three beds labeled with the disney line. And the only one that has the tencel top like the picture somebody took above is labeled as being really soft, but I didn't find the bed that soft - rather, of course it was & had a pillow top for sure, but my wife and I are both VERY LARGE PEOPLE and so often get swallowed by "soft" mattresses, and that didn't happen AT ALL, so I thought it was firm to extra firm, but with a thick pillow top.
At least the sale goes until June 15th, so hopefully one of the folks who pulled the trigger and got a mattress will be able to report back before it ends!
