I recently used the valet service and was generally happy. A very easy and stress free way to travel. The shuttle divers and desk associates are all very helpful.
I would have given a 4 star rating, however the detailing service I added did not meet my expectation. When I got my car back, it was cleaner than when I had left it, but they seemed to have missed spots on the body, windows and mirrors were cleaned properly. For some reason they decided not to clean the corners of my windshield and side mirrors.
I would use the parking service again. I will leave the cleaning to others who take a little more care.
