Entertainment for dd's 5th in SW London?

[Elibean]

She's just started school, so has a small group of friends from there plus small group of old friends from pre-school/family....will be at least 25 kids in all so am hiring her old pre-school hall.

I thought an entertainer of some sort would be a good idea - and looked at Perform parties as dd v keen on music/drama, but they won't allow younger sibs to take part so thats not great.

Any recommendations or thoughts welcome!

Action Station has been recommended by several MNers (can't remember the URL but search old messages or Google).

Thanks, will google

Found an 'Action Station' thats a sort of commando style action centre....not dd's cup of tea, she's more fairies and musicals!
