We stayed in a deluxe alcove a few years ago. We were a party of 5 (3 adults and 2 kids). It was fabulous. The pull out sofa was not comfortable, so we put the mattress on the floor. That was comfy. The roll away bed was super. I'm not sure if there was a charge for the roll away bed since we booked on points.
If you need to wash laundry, you have to go to the Dolphin. The up side to that is that the laundry room is right next to the door to the pool complex. The kids swam and the adults checked the laundry.
Quick service is also in Dolphin, but we only ate in the resorts once. We are usually in the parks.
