Harrogate Mumbler visited in August 2013 and it was great. Unfortunately as it was the summer holidays the Peppa Pig bit was rammed. Having said, that there were bits within the Peppa Pig world that didn’t have massive queues (the water jet play park, the little houses where you can just see the figures and get your photo taken) so my girls still got a good look around.
The rest of Paultons park was much less busy and it was fantastic. The vast majority of the rides are for kids- only one or two have height limits (I seem to remember 1.1 and 1.2metres) so my kids could go on most stuff.
We were there for 2 days on a Poultons mini break and could have stayed longer. We loved it and will be back! Quite often they do a buy one day get one free.
Top tips- rent a double cart/buggy for the day. The park is massive and it really gave my 2 kids longevity. They loved jumping in the littl cart rather than a pushchair.
Take swim stuff and towels for the water jets bit (big one inside the main park, smaller one inside Peppa Pig world)
