DH and I stayed in a Family Suite at All Star Music ( a value resort) in Sept. of 2006
We really enjoyed the Queen size bed, the kitchenette with the microwave, having a sofa and cushioned chair to sit on and relax after a day at the parks before retiring for the evening.
I thought the pullouts very comfortable.
They are designed so the back cushion and seat cushion of the pullout support the pullout. There is no metal bar to hurt the sleepers back.
Info thread--Pullouts in Family Suites at ASMU with photos of how the pullout is supported.
We stayed there this summer and it does sleep 6. We are a family of 5 and had a wonderul time. I have to stay next WDW trip I will not stay anywhere else BUT the ASMU family suites.
