Staying on site at shark cabins

Hello everyone!

Hoping you can all help me out with a couple questions Im stressing about with staying on site.

Firstly, it'll be my first time staying at thorpe park and first time at the park for about 10+ years so not sure on how most of anything works with regards to hotel stays.

The website mentions you get free parking for staying on site and 2 day park tickets (I'm going on a Monday coming back on the Tuesday) and was wondering if you are able to visit the park before the check in time and also still use your free parking on the day of arrival before the check in time and same thing for the check out day.

Secondly, can you leave the park and come back after park closure and still be able to get in and out (I saw someone on here mention the food in the evening isn't the best and to go to the two rivers retail park). So if park closes at 5 are we able to drive out after 5 and then drive back and park up again.

Thank you everyone for any help :)
