Over on the WDW boards, there's often chatter discouraging people from parking at places like the Boardwalk, or the Monorail resorts to avoid paying for parking when they are going to the parks for "a few hours". I think the same thing applies here to DTD at
Disneyland. DTD parking is intended for DTD. If you are going to spend more time in the park than at DTD, you should either pay to park at one of the main lots, or pay the hourly parking rate at DTD after the free period has expired. Having a validation for dining at a TS restaurant is a valid exception. Buying a soda at AMC without seeing a movie and then heading into the park for 5- hours is not.
