After a sales pitch at Westin Beaver Creek we just purchased a 2 bdrm 1 week. The sales rep recommended we buy a unit at Westin in Cancun which gives us 148,100 points. We have no intention of vacationing in Cancun but will at many of the other Starwood vacation resorts or Starwood hotel properties. Did we make a good decision? Any advice? We have 10 days to rescind.
