Used Fairfield Inn/Jefferson Blvd @ Providence last week.
Best deal I was able to find. It was thru Hotel Reservation website. Thursday night stay, parking up to 14 days, free shuttle (only until midnight, so the taxi cost us $8.00), free continental breakfast all for $95. Did not use the pool, it was outside, but we arrived late, and had an early flight the next morning.
Good luck!
