I would request Lahaina towers for the least walking from the elevator to the room, and from the garage to the elevator. I would also ask for the highest floor possible. There are plenty of lawn chairs on the grass and it has good shade.
If you do get placed in the napili towers, you may want to ask for room 01. It is right next to the elevator, but has a modestly impacted view based on the angle of Napili.
Enjoy your trip!
Best,
Greg
