I love Kimpton hotels. They are extremely pet friendly and it's so nice to see dogs in the lobby of an upscale hotel. Pets are definitely becoming more and more welcomed at places like this, which is awesome.
We are at Big Bear right now with Porkchop, actually. We drove almost 3 hours just so he can see snow. He was confused at first, but then rolled around in it and ran like a crazy dog. I told him not to get used to it since neither of us likes snow, so he'll have to settle for the beach after today.
He will be traveling with us just about everywhere we go. We used to fly once a month before we got him, so now we're planning lots of driving trips so that he can come along. This site is great for pet friendly places around the country:

Have fun in Boston!
