My husband and travel out of BWI often and always park at the Doubletree. This time we had a little bit of a twist. We made reservations for 12/10-17 but unfortunately we had a medical emergency that made us extend our trip for 8 more days. We went on the Book2park website and easily found where we could extend our reservation. When we got in last night (10:30pm) I called the hotel and before I got the hotel operator on the phone there was the shuttle bus waiting curbside, like he was just waiting for us! I told him he was my Christmas Angel.
