Anyone have any information or comments about the Polo Towers or the Hilton next to it. I have a timeshare I can use. The Marriot as well.

If you are talking the Elara.I believe there is a Marriott close to the Polo Towers the rooms are nice but there is security at the elevators 24hrs a day.
Polo Towers is okay the rooms have kitchens and living room area/sitting area.
There are two towers and I think you need a key to access the floors if I am not mistaken(things could have changed)
If I had to pick I would go with the Elara very nice rooms but there is security checking for keys at the elevator.
Enjoy and have fun
