Need party ideas for a 9yr old boy in Orpington/Bromley please!

[LifeInTheSlowLane]

That's it really! New to the area and my son's birthday is in March so was hoping to have an indoor party somewhere near Orpington or Bromley. Does anyone have any good ideas? Many thanks!

bump - anyone??

There is Adventure Kingdom in Bromley civic centre and the Buzz Zone in the Walnuts leisure centre but I'm not sure how suitable they would be for a 9yr old really. These places are usually full of younger children and a party of 9 yr boys might have trouble keeping themselves out of trouble in one of these two places. My son is having a jelly fight party soon. Literally lots of jelly to chuck around in the garden? Just an idea. Hope you work it out and have a great party.
