I see why people can easily go for 2 days at Paultons Park, we didn't see all of it and we were there almost the whole day.
Aside from buying ice creams we didn't eat at Paultons, took a picnic with us so can't comment on food. Entrance price, well Charlotte is petite and still under 1m, but if she was over its just one price for all, which I think is a bit steep, but if you compare to say Legoland its good value.
Only downside were some of the toilet blocks could have done with sprucing up, liked that all the toilets had an adult and child seat though.
If you go and its a nice day make sure you take swimming costumes and towels for muddy puddles and water kingdom.
