FYI
If you are staying at the Marriott, and have a car it will cost you $18.00 / day. It's valet parking so if you need to go anywhere or get something from your car your going to have to wait while they retrieve (also probaly tip them each time.) Also if you are checking out on Sunday then you will probably need to leave your luggage at the front desk.
See you at the show,
