I'm going to be in Boston August 27-29 for an event, and I'm trying to find a good hotel with good weekend rates. I think I've narrowed it down to the Westin Waltham or Sheraton Needham. the Shearaton is a little closer to where I need to be, but the Westin is $10/night less expensive and looks like it might be a better hotel (is that true?). A big plus is that both of these hotels have free parking (I will need a car since the event is in the boonies).

The Hyatt Cambridge is $30-$40/night more, does not have free parking I believe, and is even further away from where I need to be, so even though I am a big Hyatt fan, they lose out in this case (and the Hyatt by the airport is too expensive to even consider)!

So any comments on the two hotels I'm considering or any alternate suggestions (the event I'm attending is South-west of Boston, down by Foxboro).
