Pretty much what sovereign said. I've been to several and they've been great fun, good for inspiration and getting ideas. The ones I went to had lots of stalls for all different things associated with weddings such as jewellery, clothing, flowers, entertainment, transport, photography, cakes, you name it really! Most stalls had discounts for the day for example I got 10% off my tiara (kind of like a show price discount). There were chocolate fountains, ice sculptures, magicians, free bucksfizz and sweets, competitions, a catwalk show, dance demo, hair and make up demo, and an opportunity to try dresses on. They had lots of different types of decorated cars outside to look at and leaflets were handed out here there and everywhere lol. Personally I think they're fantastic and a good day out if nothing else! I've certainly found lots of suppliers that I am using via wedding fairs. Enjoy it, i'm sure you'll see lots of things you never even thought of before!
