yo dyno...i'll help you promote, and even get you/recommend some local acts/artists/food vendors if you need something for that extra room. just gimme any details once you get em settled.

but yeah, i think it depends on how you are gonna schedule the DJ(s) if you are doing one floor. if you can for sure get ALOT of non-bboys/bgirls to attend, i'd say go for that extra room so they got some place to lounge/chill/conversate at. if the party is mostly bboys, i'm willing to bet it'll turn into a standard cypher jam...if so, go for one room...then rotate the DJs to give the non-bboys some dance time.
