Just back from ASMu Family suites and they were great! Great having two bathrooms and also the little kitchen area, especially the fridge. We were there for 2 weeks and we had plenty of space! My DBs slept on the pull out beds and said they were ok not really comfy but ok. If you do a search on this board you will find a great review of the suites and photos.
DH and I stayed in a Family Suite at All Star Music ( a value resort) last Sept. (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 meatle bar to hurt the sleepers back.
