The floor has outlets available but you may have to run extension cords depending on your location and how far it is from an outlet. As far as alcohol is concerned, I have seen it served in "after hours" events and in an open bar setting with wrist bands for verification. I have not been at a "family focused" event so unfortunately I can not accurately answer that portion of your question. Sorry.
Interesting
Im not sure I really don't know about that area ...
