I am a local who came down to Mandalay Bay to meet up with out of town family. It was my first time parking at a MGM resort since the new parking fees were put into place. As a local, I have always enjoyed the flexibility with parking on the strip including valet. I use it almost exclusively for simplicity and safety when I am alone. I usually tip on the way in and on the way out as I know the valet staff rely heavily on those tips. Well...shame on you MGM for now charging $13 for 4 hours of valet! I really hope you are paying your valet staff instead of them relying on tips now! This cannot be positively affecting your staff and it definitely impacts my decision on which resorts I will frequent as there are others to choose from that will allow me the simplicity and safety that ,as a customer, I deserve. You have so many other options for earning money.
