Our reduced group parking rate at the Marriott is $8 a day with in and out privileges for that day.  How it works is you park in the self-park area, when you leave and present your ticket, ask for the "Camp Hollywood Rate".  Be sure to get a receipt and present it on your next exit to prove you've already paid that day.  Please note that parking availability is not guaranteed, and other parking lots in the area will not honor this rate.  Lot may charge up to 80 cents in tax on top of the $8.
