Rev. Ann Fuller is spot on with her suggestions. So is Dr. Shapiro; however, I would like to say that you should have both the labels/stamp and your own personal business cards. There is a place for both. If you're filling out raffle slips, the labels or stamp is perfect, but the business card may not be appropriate. However, if you want to leave your contact info with a vendor who is not holding a raffle, the business card is ideal.
And some additional suggestions:
It may seem obvious, but wear comfortable shoes. By the time you navigate the aisles of the bridal show, you will have walked miles. Also, plan to dress in layers. Expo venues can be hot, cold, drafty, etc. If you dress in layers, you can adjust your attire accordingly so that you're comfortable.
Be sure to bring your appointment calendar. Vendors often have special offers for those who book a consultation while there at the show. If you've identified one that you'd like to meet with, you'll know when you're available.
Bring something to write with, and take notes as you move through the show. By the time you've visited the booths of 3 photographers, 4 DJ's, 3 caterers, etc., you'll be on 'information overload' and find it difficult after the event to remember which ones you may want to follow up with. Just jot your notations on the literature they hand out, to help keep things straight in your mind.
Also, you might want to check with the bridal show organizers about what vendors have committed to being there. Our local bridal shows tend to draw mostly photographers and DJ services, with perhaps only one representative from the various other wedding services. If you're going to take the time to go, find parking, and pay the admission fee, you're going to want to be able to visit the kind of vendors you're looking for.
But, do attend one or two just for fun, if you can. It's a great 'girls' day out' experience, and since the vendors are all in one place, an efficient way to "shop" for just the right service providers for your wedding.
