Once in the park can u exit to go gef food and come back

Yes. Make sure you get your hand stamp

Yes but you need a hand stamp and there food inside but its expensive so I recommend getting food form Valencia and Newhall area local food locations like McDonald's and wendy's and red lobster is Expensive.

Yes you just get your hand stamped for reentry We pack a lunch and eat at the truck when we get hungry then we go back in

Yes, if you can, you only have to ask for a stamp at the exit, but you will have to pay parking again when you return ...

No
