Follow the link, put in a date in February and a pop up appears telling you it's £50. Great dates for me, I live in Wales and our half term is a week earlier than England, so if you try during England's half term it probably won't work.
OP how are you getting £50?
Great family day out
I went there as a kid, was hoping to meet Chewbacca, never been so disappointed :(
I can't find this for £50 - only on a room only basis and without entrance too Wookey Hole.
