Yes, stayed in one last summer.
Basically it's really a two roomed hotel room. It's not that much of a kids suite. Ours had a table in the room and a photo of Spiderman.
The room is excellent though, because of the extra space. the kids room has two single beds and a tv. There is a walk in wardrobe, with loads of room. There are two showers, two sinks and a bath, but strangly only one toilet..
For me I wouldn't have paid full price for the room, but for a king suite price as an upgrade is fine.
Personally, I would sell the rooms as two bedroomed hotel rooms.
The photo below was on the wall above the kids beds and I love it..
