SW London/N Surrey mums - soft play centres for under 7's. How much do you pay?

[amidaiwish]

Building on my 2nd hand clothes shop, it seems there is a real need for a soft play centre in the Teddington area.

Before i can see if it is financially viable, can you let me know:

a) what you pay for a session of soft play per child / per age

b) what soft play you go to.

Thanks.

that should of course be "which" soft play you visit. oh dear. maybe grammar lessons as an add on??!
