I went to an oceanfront hotel last year and I discovered upon arrival that all they had was valet parking. I didn’t like that one bit, but IIRC they didn’t charge for it. I did strike up a conversation with the valets and tipped them at the end though. I felt like I needed to talk with them a bit if I wanted my car treated with respect. I was on vacation though, having my car parked in some unknown spot was a worry I was not needing.
