I'm thinking of something like this. If we are able to get the cabin (7586) that has a queen, the convetible sofa and the muphy bed, I was thinking I could bring one of these - just in case sleeping 2 on a sofa doesn't work out. I'd really be happy if we don't have that top bunk! I just picture the little monkeys climbing and jumping . . . and having so much fun on the "playground" until someone cracks a skull - lol
