• The Centre is the venue for your party: we do NOT supervise your children. You bring a ratio of free adults (1 per 4 children) who have responsibility for the children at all times. 

A member of staff will be your party co-ordinator on the day and will meet your group, advise of timings, lead the tour, activity and generally oversee and be on hand to answer questions. They will not take responsibility for your children.

•You will be required to sign a Birthday Party Code of Conduct ensuring that the adults accompanying the party will be responsible for the safe conduct of the children at ALL times. 

•A payment for the minimum 8 children is required at the time of booking, which is non-refundable if the party is cancelled with less than 3 weeks' notice. You will be charged for the minimum of 8 children, even if less than 8 attend.

•For daytime parties the balance for additional children / adults / siblings is due 5 days before the party. 

•For twilight parties the full payment is taken at the time of booking. 

•Child membership holders do not qualify for any discount on parties. 

•Adult membership holders can accompany a daytime party free of charge (food additional). 

You can arrive 15 minutes ahead of your party guests and we request everyone leaves the site no later than 15 minutes after the party end time.

•Drop off / pick up for daytime party is in our entrance reception / shop. We do not permit anyone to enter unless they have been paid for and are on your party list. If families dropping off / picking up their child wish to enter The Centre, they must pay the admission price.                       

With a twilight party there is no option for additional children / adults to stay at The Centre

•Children & adults should dress appropriately for the weather conditions especially if they wish to use the outdoor areas or have booked a twilight party. Most areas have no heating.
