I guess a lot depends on what you are used to. I expected the rooms to be really tiny, based on other reviews I had read. It turned out to be just fine. It's exactly what we are used to with the other types of hotels that we frequent. If you're used to a luxurious and very roomy hotel stay, then you might be disappointed and find it too small.
We were at ASMo last week, and found the rooms to be just fine for us. We had two adults, two children, and an infant. We rented a pack-n-play. For the amount of time we actually spent in the room, it was just fine. I would certainly stay here again.
Hope this helps!!
