Yes, there is. Glad you asked. From the passholder site it is says for Preferred AP holders: Pay for 2 hours of Valet and get the rest of the day for free. So it looks like you can valet park for the day for $10.
I think it's awful to charge for parking for guests that are already paying over $200-300 a night for a room.
When I was there last time it was $12. Now it's gone up to $14 if I could find a convenient way of getting rid of my car for those 4 nights I'll be at the hotel I would.
I hear ya on that cause I was going to rent a car this year but after figuring in parking and the gas plus the rental we just couldn't fit it in our budget
