I set up a couple tables downstairs for LEGO PLAY, my daughter's room was the Art and Craft rea, the living room was where they could play Lego Rock Band (very fun). The kitchen was for the adults.
I downloaded invites from Lego.com and also invited friends on Facebook- made an event!
There was a cool site out that was far more into it than I was:
The party started at 3pm- free play, 4pm- pizza times, 4:30- gifts/cake eating and 5 was suppose to end of the party but it kept going to till 10pm. LOL! The adults I think had more fun than anyone :0. Fun was had by all!
The only thing I regret is I TOOK NO PICTURES! I busy with the party to think about pictures...UGH!
