Check out these two bulletin boards: www.betterbidding & www.biddingfortravel.com . I haven't looked in the Vancover threads for a while.

I bid for my sister & brother-in-law for two nights this past Sept. I bid 3* by the airport & got them a mediocre hotel. (adequate since they had an early morning flight out) . I also bid 4* near downtown and the Hyatt came up. The Hyatt is a nice hotel and well located. They liked the Hyatt alot.
