The one thing we found was the elevators or slow or busy very often, so being able to just go up a couple or down a couple of flights to get to the major things we needed, was great as we took the stairs alot. For the Wonder we were on deck 5(didn't chose it, we got upgraded for free) but it was nice being in the middle. For the Dream, we chose deck 7 since the ship is larger, hoping for the same convenience.
