If you get there after your reservation time will you still be let into the park

Yes, they dont care.

Yes.

Try to get there early if you do not have a member pass or a season pass you will be parked far away from the entrance and it takes longer to get in

Yes I had a 10:45 reservation and was in @ 11:15

Yes you will

After your time yes, I only saw people get turned away if the were 3-4 hours early.

My boyfriend and I had a reservation around 11am and we were let in early, around 10:45am.
