I checked various Disney-lodging sites and found many 3*'s going for $80-$100 for those nights (Hampton Inn-LBV, Quality Suites, Doubletree, Courtyard by Marriott, Grosvenor). I would think $60+20 would have gotten me a room. I'm going to try again today using a different net address.
I found Country Inn Suites for $71 and might opt for that if bidding doesn't prove fruitful today. (I'm doing this for someone else. I have been spoiled by past bargains through Priceline and wouldn't personally pay $71 for Country Inn, but he's willing.)
