We ALWAYS do this out of Baltimore when we go to Disney at least 3 times a year and we stay at Hyatt Place in Litihicum. Anyhow, the rooms are so large you won't need a cot. We always put 5 in our room and we book a room with 2 double beds and we have no problem. The Hyatt Place has a living room with a large secitional/sofa bed that you can easily sleep on. This is how we sleep. Me with one of my girls age 8 and my Mom with the other girl age 7 and my Husband sleeps on the sofa bed in the living area, no sweat! Also they have great pricing for Park, Sleep, and Fly
