So my sister is on leave in a couple weeks and wanted to help plan her own wedding. We are 90% sure that this will end up being a destination, but just in case, she wants to check out local vendors. She is interested in going to a wedding expo. I've never been to one so is there anyone out there that can tell me if these things are really helpful or just a waste of a couple hours? Should she bring her checkbook - do people actually get their vendors at these things? The whole thing seems a little crazy to me.
