I'd bid $80 for 2 1/2* level using just Airport and Old Port zones and been rejected. Three days prior, I'd also been rejected using Airport, Old Port, and S. Portland zones at $75. Both this and Sheraton previously reported are in S.Portland - Scarborough zone.
This is more than I've paid previously for priceline hotels, but I went through several rounds of bidding to get this accepted. Was bidding Airport, Old Port, and S. Portland zones. Best online rate for this hotel on this nt was $189.
After several rounds of bidding with Airport and S. Portland zones, my bid was accepted. This was an upgrade from a 2 1/2 star to 3. This is more than I've paid previously when using Priceline but still better than the lowest acceptible rate I could find otherwise ($130 at Comfort Inn).
