I'm looking for a holiday park or self catering accommodation with plenty to do for the age range of 9-12.
I have one animal fan and his brother is a fan of playing pool and darts. Both love swimming and hiring those pedal go karts. And general exploring within a safe limited area such as a holiday park. I can't camp but happy to do a lodge or static caravan.
Last year we went to Duinrell which ticked lots of boxes.
This year i would like to visit the south coast or SW eg Sussex Kent Hampshire Isle of Wight Dorset Devon.
Or to get on a ferry eg Portsmouth or Poole to go to northern France or Channel Islands. (Max 2 hours drive the other end).
I would definitely second/third Tapnell Farm. We go every year and there's so much there to please so many different ages. The accommodation does book up very quickly (every year we book for the year ahead while we're there) but you can visit for the day. And you can finish the day with a nice meal at the restaurant, The Cow Shed.
