Thanks GM Mike, for all your help so far. Yes, it is a bit confusing, but I understand these are the hoops one must jump through in order to get a (hopefully) great bargain. Okay, as you suggested I entered bid amounts, and here are the (possibly unrealistic) numbers I came up with for maximum bids. World Trade Center, Cambridge, Downtown Boston, Copley: $50 All Other Zones: $40 As far as quality level, I'm perfectly fine with a 1* EconoLodge, although of course I'm hoping for something better. But 1* is okay with me. And yes, I would consider leaving the car at home if parking is expensive. Might I have a better chance with Hotwire? I would be happy to try that as well - but I suspect that topic should be discussed in the Hotwire forum?
