We've just returned from a rather wet week in Cornwall and i wanted to pass on a snippet of info that we only learnt yesterday which was too late!
When you pay full price to get into Dairyland, just outside Newquay, you can claim a free pass that will give you unlimited entry for the next 7 days.

DS aged 4 loved it so much he cried when it was time to leave. I highly recommend it, especially as you can return for free.
