Every Poly room and virtually every BC room has a daybed. You don't need to worry - if you have a party of 5, you are supposed to automatically be assigned a room with a daybed. The only time I had a problem was at YC when they reassigned us on arrival (because our assigned room smelled of smoke), and the CM forgot there were five of us. When we realized the new room had no daybed, we just came back and got her to reassign us again.
