In my area, in the last couple of years, bridal shows have almost become wedding photographer shows, with 13 out of 39 vendors at one show last fall. Competing with a lot of "Best Buy" photographers selling $500 packages on price alone. I guess my advice would be to have a nice display, i.e. at least a few albums, a couple of large canvas wraps, a slide show running, but most importantly to educate potential brides as to what to look for in the quality and consistency of the photography itself. Anybody can get any kind of book. What fills that book (the quality of the photography) is by far most important and, sadly, sometimes the most difficult thing to get brides to focus on when the guy fifteen feet away is giving everything away and it isn't really worth a damn. Keep the focus off price and on what really matters. IMO
The purpose of an open mind is to close on something.
