I asked this question yesterday to the WDTC and was advised that they do not have roll aways. Yep, they will give you a sleeping bag. Some of the Std view rooms have a daybed and you can get a Queen room with bunks, again I think only std view.
We were only able to get DTD view for our dates in Sept and I have been told that my only options are 2 Q or 1 K. So I have requested 2 Q as I don't want my 2yo on the floor. He is too big for the pack n play, which they do provide.
HTH
Cheers
