Since charging for valet parking, parking sucks. The staff has no incentive to hurry because their tips have dropped. I was good for $10 tip or $20 to be up front in the past. Now takes so long I give $2. Literally $2 tip. I feel guilty so little but now it takes too long to get my car. It's unfortunate that something so little becomes so big. In total I probably pay less than I used to when it was free, but I leave more annoyed and come to the hotel less often. Some of their restaurants are fantastic so if I want to go I deal with it, but not happy about it.
What happens, from what I can tell is the guys don't make as much so they don't work as hard and in turn causes people to give less.
