Interesting. I took a look at your vendor info, and noticed the bit about changing from a full-time vendor space to a 3-hour Fan Fair. This actually discourages me from wanting to come to the con, because while my partner's T-shirts and some of my jewelry would certainly appeal to your fan base, 3 hours is not nearly enough selling time to make the trip from Houston to Arlington worthwhile. Perhaps you could suggest that for next year, there might be a small full-time vendor room for... I hate to say "professional vendors" because that sounds so judgmental, but people whose primary interest in the con is being vendors, and then also the Fan Fair for people who want to sell stuff secondarily to participating in the rest of the con.

Or I could be all wet. Have you had any major vendors at this event before, people who make their living (entirely or or a substantial portion of it) from convention sales? If not, then this may be the best course for you. I was just curious and it sounded like fun, but there's no way I could do it under the current arrangement.
