Tried $100 for Union Square East for 4 stars, didn't get any luck. Added Nob Hill and upped my bid $5. Was hoping for better than the Hilton, but the location looks good.
Bid $18 and $19 for intermediate and standard size respectively, and no luck. Hit on $21 for fullsize. With taxes = $140 / 4 days, which is about 40% off listed price. Used the PRICELINE link as always.
First bid $135, second bid (added the airport which doesn't have resorts) accepted for $145. With fees = $175. Very happy, regular rate ~$370. Thanks better bidding :)
