Valet at the Marriott
Many event organizers will also provide parking validation if you park under the hotel.
Better park it in hotel. They have valet parking. It shouldn't be costly.
Under
Just drive around the back and go into the parking garage. Not a bad price.
Underneath the hotel in the on-site parking garage. Parking prices, if not comped by your event, is very reasonable. ($5-ish??)
