I need party game ideas for 30 children tomorrow, HELP!!!!

[137wallis]

My ds is having a birthday party tomorrow for 30 children, I had booked a disco but he's just cancelled so I need ideas for party games for 30 children aged between 3 and 8, the majority are 6 though!
so far have thought of musical bumps, musical statues and dancing, but can't do pass the parcsl so any other suggestions will be greatfully received! Thanks

Thanks so much for all your help ladies, mumsnet to the rescue again! Party went off without a hitch, all the kids came plus 2 siblings so 32 in total! but they all behaved and no I didn't loose anyone! tryed the marshmallow game (gross but the kids loved it!), corners, a great paper throwing game I found on the internet and the kids loved, musical statues and musical bumps, and got a party dance cd so they were all exhausted by the end of the party! it was great fun and I think all the kids loved it, Thanks again for all the suggestions

I think you deserve some sort of MN award

Thanks, wasn't as bad as I thought it would be, even though the other adults that were supposed to come didn't so there were only three of us! went to bed at 8pm though! just after the kids. thanks again
