|Subject: Boston - cheap accommodation|
In Boston people often get the best results in hotels by using Hotwire or Priceline (add .com), not knowing what hotel it is before committing to it. I can't tell if you can use these without a U.S. address (which may need to match your credit card address). The Hotwire site asks for state and ZIP code. I just entered a search for Boston this Saturday; they show an upscale downtown hotel for $62. That might be an indication of what to bid on Priceline if they let you.
