Hpw much is the valet parking, if we are staying at the hotel?

I believe it is $25. But if you purchase it before your stay you get 20% off. And considering park parking is $20 it's a pretty good deal.

I don't think there's valet parking, regular parking $20, preferred parking $30

Park it your self not worth valet

Not sure about Valet but Preffered is $30 and Regular is $20.
