We had 5 in a standard-sized AKL room (8 days) and CSR (2 days) in May -- dh, 12 yo, 4 yo, 2.5 yo, me. The only time we were ever in our room was to sleep. While we had a portacrib at both resorts, the little ones chose to sleep together. At AKL, they slept in the top bunk. At CSR, I fell asleep with the little ones in one bed; and dh and ds slept in the other. We had plenty of room and experienced no problems. I had plenty of reservatins about this at first (We usually have much more space but had been unable to reserve a second room due to late planning and the Memorial Weekend.) However, we did just fine. In fact, it was less nerve-wracking than checking on my kids in another room. They are known to wander!!
