There is enough room for a port-a-crib at the foot of the beds - and we were still able to walk around them. Some of the rooms are bigger than others - I'm not sure how they classify them - you may want to ask. I would say there was room for a sleeping bag - but you'd want to roll it up out of the way in the morning to walk around. The rooms are bigger than say - a Super 8, but smaller than some bigger hotel rooms. We really enjoyed our stay there, and had no problem needing the room for the crib.
It depends on what you're used to! We're really not in the room too much - and it was a wonderful hotel - great breakfast. had its own shuttle, close enough to walk, quiet, and very clean! Can't recommend it more highly!
