Hi Dawn,
It's really a matter of preference. The New section is very nicely done and parts of it are very close to the lobby and therefore the bustops. Parts of it are also very far away, those are some of the longest hallways I've ever seen!
The old section is closer to the restaurants and pools but further from the bustops and lobby.
We really enjoyed the new section but we were the first room off the elevator. I think I would not have liked it as much if we were WAY down the hallway. The older section near the pools is nice but is loud almost all the time. In the new section even though everyone walked right past our rooms from the elevator we almost NEVER heard noise unless people were yelling or screaming which was rare.
If you're going to spend a lot of time at the pool/playground, choose the old section, if not, go for the new section, it's so lovely!
