Please note: WEEKEND BOOKINGS CANNOT BE CHANGED AFTER 3PM ON THE FRIDAY BEFORE. PURCHASED TICKETS AFTER THIS TIME WILL NOT BE REFLECTED ON YOUR BOOKING. You can only purchase additional tickets if you already have a Group Booking AND have spoken to us first by calling 020 8300 0084. Please ensure the original booker buys these tickets using the same booking email address. We reserve the right to cancel and refund tickets which do not meet this criteria.
