Hey,
Ive been to a couple of soft play centres.
My favourite one is Chucklebutties in Belper - not really THAT local, but its nice as its on the side of the old mill, has windows down one side and overlooks the water. Luca loves it! Its definitely worth the short drive to Belper... its under a fiver to get in (babies under 1 are free) and you can stay as long as you like.
http://www.chucklebutties.co.uk/Ive been to Hickory Dickorys which is just by Kingsway, but I wont go there again, I didnt like it. The lighting is terrible and you cant see your little one when they are inside the climbing area... other people might like it though, I just didnt get a good feeling there.
