We were just there in January -- My DH, DSs (6) and (8 mos)
The bed for the adults is nice and large and could even fit an infant if you were so inclined.
The couch turns into a nice twin size (or a bit narrower) bed. The playpen we put next to it - between the 'couch' and the desk. They provided the playpen, we brought a sheet for it. It was crowded, but wasn't too bad. Would have been crowded even without the playpen. If you can afford a category 3, I heard that's much better. My friend stayed in one last fall.
The biggest obstacle in our room was the stroller. Trying to get around it and folding it up some place at night.
Our friend who got the category 3 upgraded during check-in so they had to pay only $800 for the upgrade. We checked on the upgrade when we sailed but they were sold out.
Hope this helps.
