• Does the booth come with an attendant? “You want someone there all night who knows the booth and can handle any issues that come up,” says Lynn.

• Do you have back-up equipment? Be sure your vendor has replacement parts on hand or another booth he can use if necessary.

• How long do the photos take to print? “If it’s longer than 20 seconds and you’re paying more than $1,000, you’re not getting your money’s worth. Taking that long to print is a sign of an older machine,” says Eshelman.

• Can I see a sample photo? You’ll want to make sure you’re happy with the quality of the snaps. Also find out if you have a choice of whether the photos are printed in black-and-white, color, or sepia, if that’s important to you.
