We had 3 kids with us in June and had GV conceirge. It was the greatest room. It was first floor about 1/2 way between both ends. Sorry, I don't remember the #, but it was perfect. We spent a lot of time around both pools and it was so nice to be able to run in and out of the sliding glass door. It also made it easier to leave that unlocked, since the kids kept loosing their key cards.
The ends of the Hawaii building have plants in front of the rooms, so they weren't as easily accessible. You would have to run right in front of other peoples rooms, which would have made me feel uncomfortable.
