Visited Towers on the Grove last September. It's rather quiet around the hotel, but like others have said, grocery store and other amenities are close enough to walk to.
Sales staff was pretty high pressure during the "Owners update" but just walk out after your minimum required time and you should be okay. I think we got $75 for Greg Norman's steakhouse (which was very good).
Pool is under shade, but the location in terms of the beach is great. You can rent chairs from the hut on the beach.
Room setup was a little weird (walk through bedroom to get to living room/balcony, but since it was just my wife and I it was fine.
Overall we really enjoyed our stay and would go back.
