...recently stayed at the Hilton, right by the airport. I believe the crew rate was $89 ($99 maybe, but not more than that). Nice hotel. You can walk from the terminal directly to the hotel via the skybridge. If you have a day to kill, walk the skybridge over to the terminal, catch the airport shuttle over to the subway, and for about a dollar each way you can sub your way over to downtown Boston and walk around. Go to Legal Seafood (by the pier) for some good chowder.
