Centre Parcs - Day Pass

Hi, My partner is going away in a couple of weeks with family/friends to Centre Parcs in Whinfell.

She wants me to join them but the lodges are at max capacity so we can't just put me on the list.

I believe to join in the activities I need to be on the system, so it's best I buy day passes to do?

I have two options, either book a hotel close by or try and stay at the lodges as they have an air bed for one of the children.

This way I can have a drink etc and be fully involved with less hassle.

Does anybody for the day pass, do you had anything back or sign out each day when you leave?

My ideal solution would be to stay Saturday/Sunday and hopefully not need to leave on the Saturday night.

Thanks
