I think they have been open about 3 years but they are immaculaltely maintained.
What time in July are you going?
We went mid June and there were not many children there in the 5 -12yr bracket.
I would say GO GO GO whilst you can get a place - repeat returners cant be wrong!
We are now one of those repeaters - booked again already for last week June/1st week July.
Any more questions feel free to ask & I promise I will try and give an honest opinion if I can answer them.
