Sure, this trend might be picking up at weddings and parties in general, but trends are usually hot for a reason: Skip the disposable cameras and capture candids with a rented photo booth! Guests will have another great activity for the reception, you'll have even more awesome photos for your album, and face this reality: Everyone loves a photo booth!
Photobooth.net helps you find and reserve a photo booth around the country (and has a great piece of advice: Traditional photo booths need a venue on the ground floor due to their weight). And Party Booths also supplies digital photo booths, if quality is an issue.
Best and worst part: Aunt Ida and Uncle Marty may find the booth after several glasses of champagne punch and get a little frisky. Those will be shots for the album for sure!
