I bid about a week ago up to $60 with no success. I big again today, starting at $50, and was offered a rebid/win for $17 more. I declined and bid $55 and then $58 and won the Scottsdale Resort & Conference Center.
I've won this hotel in the past for this same timeframe, including last year, for ~$70. The current going rate for these dates is $114. So I'm happy with my winning price.
