For me, size just doesn't matter. As kids, we slept 4 in a double...think sideways! Thought I was in heaven when my sister and I got to share a twin...top and bottom. DH and I have a queen at home, but our cabin only has room for a full, and that works just fine...He's 6'5, and 300+, and I'm 5'10, and much heavier than my drivers license states...don't need a lot of room...we both sleep soundly, and don't move around a lot!
