We loved the Doubletree Hotel in Lowell, MA so much, that we decided to stay there for another night. Most of this much needed extra day of rest was spent in and around the hotel. The hotel's location played a great part in our decision to stick around. The Doubletree sits on the banks of a canal in Downtown Lowell, within a short walking distance to quite a few old interesting places. Tuesday morning, we slept in late, lounged around the hotel and watched a little TV before heading out in the afternoon to get lunch and go to the library.
