OMG... we just returned from FW as a last minute trip. The sofa bed is horrible - it's like sleeping on the floor. While the cabin refresh is very, very nice, they could have left the Murphy bed and put in a chest of drawers with a TV above it handing from the wall in the space where the old cabinet & TV were. We paid $400 a night to end up being sleep deprived for 2 days of our vacation.
The upside is that housekeeping has some foam pads they can put on top of that horrible mattress that makes it more comfortable, but still, the pads have to be rolled up every day and put back every night because the unit will not close with the pads in place. If you leave the bed open, the entire living room area is unusable.
The bunk beds also have the same type mattress, though it's not as floor-like.
We love FW and the cabins, but will be rethinking staying there in the future. We do not want the "chore" of making and unmaking the bed with foam pads every day, particularly at the rates they are charging.
They really blew it this time............
Beware if you are not used to sleeping on a rock hard mattress.
BTW - they also have these beds in some of the DVCs we've stayed in and won't stay there again either because of it.
