Your whole group can arrive up to half an hour before your booked time band, and must arrive before half-way through your booked time band, in order to have time to check-in.
The earlier you arrive the earlier you will be let in during your appointed timeband. If you miss your time band you'll have to wait until the the following time band - if there is room in that time band. If you miss your day - that's devilish bad luck. There are no refunds.
