Never seen any family tickets advertised Champ?
We as a family would have definitely bought them - there is always at least 2 adults and 2 kids in my party, therefore anyway to save money and see Haven all the better.
Maybe time to start advertising that family tickets are available - the website and forum would be an ideal starting point, as Mr Irving from the Whitehaven News reads these forums, and quotes from them - maybe get him to plug them in his column?
Worth a try - surely?
