Was hoping to use my christmas savers clubcard points to get legoland tickets for next year, however I will only have enough points to get 2 tickets and there are 4 of us- 2 adults, 2 children. Do I just pay on the door so to speak for the 2 children or will it be cheaper to use a 2 for 1 voucher if they're about next year.And can I still purchase qbots for all of us when there?Thanks.
