I hope you have kids - suits all ages, I would not recommend it for couples or older people(steep hills in park).
There is loads to do during the day (rain or dry), have a look at the website.
Our particular favourites - toboggan run (do not use brakes), birds of prey display, masterblaster and the biggest indoor play area in the country.
Campsite mainly large pitches on terraces of 6-8 pitches, shower blocks excellent with seperate family shower rooms, friendly wardens. No evening entertainment or bar and nearest proper shop is 5 min drive away.
We try to take the family once a year as it really is good.
Have fun.
