If the interior is exactly like the other versions (which I think it's safe to assume it is), then the entrance will be in the middle of the block on the lagoon side. Check out the front of the USH version, methinks it will be in the same spot.
The indoor queue is mostly contained on the left corner of the building according to the pic above. The outdoor queue could probably go in the empty space made available by that corner of the building being diagonal.
