Very Disappointed
I wish I'd seen the other review(s) about Valet parking damaging cars. Ours was damaged, as well. In fact - it appeared that the staff left the liftgate up (the hatch on our crossover SUV) and drove around the garage. They were so very polite to have the hatch UP when we exited the hotel, to show how nice they were to have packed our vehicle for us - and effectively hiding the damage to the liftgate. We were 2 hours away at lunch when we noticed, and immediately called management and supplied them with pictures. The one and only response ever received was, "since you had departed the premises, there's nothing we can do".
Apparently even being a Diamond member of the Hilton hotel chains (their highest level in their loyalty program) ultimately did not matter here, and the almost $900 in damage had to come out of our own pocket. Due to the experience and treatment by this one single Hilton-chain hotel, Hilton lost a customer - a roughly 100-nights-per-year customer. Marriott appears happy to have me.
