Can you enter the center and go out then come back an hour later? Do you have to pay for parking again then?

They stamp your hand so your can return. And the parking is $10.00.

Yes.. I agree with other answers.

You can going in and out ask Security upon entering. Not sure of the parking as when you enter

Shon B has the most accurate answe.

You can go in and out. Keep your ticket

I'm unsure

We were there 4 weeks ago & they were not completely opened. They had timed entry & you had to stay & couldn't come back .Check the .gov site well in advance for the date you want before you go as things change quickly. & be prepared to pay for everything. It is very good and worth reading effort at least once.

Yes
