We were a family of 11 (children aged 19 months, 5, 9,9 and 14) so had a private tour and all I can say is WOW. We were worried about the cost before hand, but it was well worth it. We spent about 80 minutes at the forest and about 25 mins with Santa. He was very believable and interacted with the kids wonderfully. It didn’t feel staged or that he was reading from a script. The elves were also great and the kids loved them as much as Santa.
Only negative was that the walk from the coach to the factory is really really short so didn’t feel like we’d just stumbled across it BUT if that’s my only complaint (and I normally find loads to complain about) it was well worth it.
