I started bidding around $55 and ended up winning at $71. I didn't want to go above $80 or $85 because there is a $25/day resort fee (wow!) so we took that into consideration. I checked Expedia and found with taxes and fees (before the resort fee), it was $143/night. Using PRICELINE bidding, we paid $83/night with taxes and fees (before resort fee). I used the PRICELINE rebidding strategy. We are excited and the reviews on Mandalay Bay look good so I think we will enjoy it!
