This is from the FAQ Section of the BC/YC FAQ forum:
Will my room have a daybed?
Some rooms at the Beach and Yacht Club have daybeds. You may request a room with a daybed, but it is not guaranteed. Families of 5 usually have first priority for rooms with a daybed. You may also request a rollaway cot to your room when you arrive. This is provided free of charge and is subject to availability.
There are two types of daybeds - one that fits a normal sized adult and the other that is best suited for a small teenager or a child. There is no way of knowing at the front desk which type of daybed is in what rooms. It's totally luck of the draw and the CM can't tell you which is in your room if you get a room with a daybed.
See Post #7 (Beach Club) or Post #8 (Yacht Club) for pictures of the two types of daybeds and various configurations of them made up in the room:
