I'm thinking of going tomorrow, how likely is it that we wouldn't be let in if we were to turn up without pre-booked tickets? Also, would any 2 for 1, or Tesco Clubcard tickets be valid??And is there any way of contacting the park this evening?Apologies for the noobieness of my questions, it was kind of a last minute decision to go tomorrow, and would just like to get the info as quick as possible.,Cheers, Dan.
