You have a choice of high/low floor or East/West view. East view is away from the strip. West view is of the strip. The west view of tower 2 would be towards the pool that's now between towers 2 and 3. I would think that a lower floor, west view in tower 2 might pick up some pool noise during the day. I believe tower 3 is now open. I'm not sure what the views are like from that tower as we haven't been to our home resort in a few years but, the east view would be at tower 2 and some of the southeast end of the strip while the southwest view is away from the strip and possibly towards the airport.
If it were me I'd probably ask for highest floor possible, east facing room in towers 1 or 2.
