Hotel tip.
If you happen to be in Boston and feel like splurging a bit, this hotel is great. (Not quiiiite as hip as it sounds on the web site, but still very, very nice.) I got a good deal by booking the night before I arrived. And I discovered this a.m. that it's only a half block from the T (subway) which will get you all over Boston for about $1.50.
