Hi Pitter,
I think the patios seem more secluded because of the foliage that surrounds them. When you're on your balcony, you can't see anyone on either side of you, but people walking through the resort can see you and you can see them. Also, not that this is a big deal, but the elevators are in the middle of the longhouse, and if your room is on an end, you'd have to walk a little. Now, this isn't a big deal to us, but to some it is. When we stayed in 3010 in Tahiti, we usually used the stairs on the outside of the building because we were on the end. We only used the elevator if we were coming from the TTC or when we checked in/out.
I also think I'd prefer a patio because there are lots of ducklings and other cute animals that roam the grounds. It's fun to watch, especially if you have kids.
Hope this helps!!!!
Have a GREAT trip. Wish I was going.........
