BLT sleeping arrangements

[Katie10]

So I am traveling with my DH, DS3, DS9months in May 2015. DS3 has outgrown the crib and pack n play since our last Disney trip. I'm trying to come up with some reasonable sleeping arrangements so that everyone can sleep comfortably.We have a 1bedroom at BLT (lake view). I wanted to put my DS9months in the pack n play in the jacuzzi area of the master bath. I wouldn't feel comfortable with my DS3 to sleep in the twin pullout chair in the livingroom area by himself. What I was hoping was that the mattress on the chair will just detatch from the chair so i can lay it on the floor in the master bedroom. Does anyone know if this mattress detatches? My other idea was to use the couch cusions on the floor with a sheet over it, but, I would prefer not to do that.
