Yes you can get your hand stamped go out to the car and return during the same day. But don't forget to get your hand stamped.

Yes. There are picnic tables provided in the parking area near the entrance for this use.

As Leah stated, get your hand stamped so you can get back into the park.

Yes

Yes you can.

Yes you can bring your own food and eat it in the parking area. I would recommend eating in the car as there were hundreds of small black flies in the parking area when we were there last week.
