Here's another vote to stay in downtown White Plains. The Residence Inn or the Courtyard (over in Rye) are apt to have decent weekend rates for a Friday night, and both are a 15 minute (at most) cab ride from HPN. The Wellsley's terrible, and though it's in Armonk and closer to HPN, it's a dump. You can also check the Renaissance or the Crowne Plaza in White Plains. Or you can call me and I can rent you a room in my White Plains house very cheaply! Just kidding.
