How much space is needed for the photo booth setup?

Our photo booths require a minimum space of 4' wide x 6' deep for a minimal setup. An eight foot ceiling is the minimum height for one of our backdrops.  If you have lower ceilings and a custom backdrop, we can make it work (ie, inside something, or sitting down).  The optimal space would be 8'x8' or 8'x10', that gives your guests more room to get around, a prop table, etc.  The more room the better as it's common for our photo booth to draw a crowd and a line of guests waiting to use it. We also need access to a power outlet nearby (generator optional for outdoor or remote areas).  WIFI is preferred, but not required.  Digital sharing, QR codes, and social networking does require WIFI.
