HPN option
We just stayed (last month) at the Renaissance HPN and were very happy. We were treated to an unexpected upgrade, as only a silver tier member, they treated us as if we were gold - very smart on their part, here I am advertising for them. Usually I don't have such luck with Marriott.
You might want to call this hotel directly to see if they can beat the online rate. They seemed more customer friendly then most.
If you do go to this hotel and do not have GPS, you must get better directions than are posted, the hotel is hidden!
happy travels.
