The classic closed booth has been around form the beginning but it still has plenty to offer.  Besides, we kicked it up a notch with our EXTRA LARGE 8' x 8' closed booths.  They can adjusted down to 5' x 5' accommodate a smaller area when needed.  At its largest it fits 10-12 people comfortably but we've had as many as 24 people in a single photo.  We find when people walk into a closed booth it's as if they've walked into a completely different room and are willing to get a bit more silly.  Your guests who are less outgoing feel comfortable in a closed booth and are more likely to use it.  Not to mention that the Red-Carpet Experience upgrade looks great on a closed booth!
