I love parking at the Westin Crystal City when I fly out out of DCA. Everyone is always very helpful. Upon my return this time, they had to borrow a shuttle from a sister-hotel and put their sign on the front of it. I am not the most observant person after a 4 hour flight, so I would have missed it while standing at the airport curb but the driver actually got out and looked for me to ensure I knew my shuttle had arrived to take me back to the hotel. Now that's great service!
