I have a lot of clients that don't know what to do for their guest book or favors. They usually want something different than the traditional guest book (which offers room for guests to sign their names and no more), and a lot of the standard favors are usually something guests want to leave behind. I have plenty of suggestions for both, but my favorite does double duty!
They are Photo Booths! I LOVE Photo Booths. Yes, I am talking about the black and white (and now digital color) photo booths that probably all of us made silly faces in at the mall at one point in junior high. They are so much fun and a great way to create a playful environment at your wedding! You can provide costumes or silly items to increase the fun for your guests or leave it as is.
The easiest way to utilize the photo booth photos as both favors and for a guest book is by providing a scrap-like-book with double stick tape and pens. Your guests will stick their photos in the book and write a sentimental note about the day next to each one. You should have a note or sign on the guest book table (or booth itself) that lets them know they should take home and leave behind some of the photos they take. For example..."Please take as many photos as you like, leave some behind for us to share, and take some for you to always remember..."
How do you go about renting a photo booth? I work with Photo Booth Services with a lot of my clients. They provide both black and white (classic) and digital booths. The classic photo booth is $1550 for a 4 hour rental use with additional hours for $100. The digital is $1650 for the same amount of time with additional hours the same. It is a really great value when you realize that it is providing two functions for you. (*Also, the rental time is equated to number of hours used. They are often able to drop off earlier and not charge you for the time, unless used. They charge a flat fee so you never have to worry about limits on the number of photos you and your guests can take*)
I have never seen a photo booth go unused. I'm sure your guest will be raving about the fun they had. No matter what, it is definitely not your standard guest book or favor!
