I don't think I'm going to be able to make it this year, but I absolutely love going to the convention.
For the folks who've never gone - Sunday is alot of fun, there are usually some cool vendors (I always buy a bunch of stuff from Kensfish.com while I'm there, I usually end up finding something cool from Franks Aquarium, and I've gotten most of my pleco caves from one of the NJ vendors) and the auction is great.
Since Charles Clapsaddle from Goliad Farms is going to be speaking, I suspect that there will be some sweet livebearers in the auction - the last time I saw him speak, he brought show quality mollies to the auction.
Which brings me to my next point. Once you have experienced Sunday -- you really need to try the full convention, the auction is just the tip of the iceberg.
The speakers are always amazing. There are generally 2-3 to choose from in each time slot, so you can almost always find something cool. This year the banquet speaker is Lee Finley, who is coming out of retirement for this talk -- he is one of my all time favorite speakers and also just a great guy to hang out with.
Which brings me to the best part - the "hidden gem" of fish conventions - hanging out with amazing "fish people" during the "unscheduled" times. I'm not really a drinker, but I always have fun in the "after hours" gatherings, and have now hung out (and drank like a fish) with many of my favorite aquarium authors.
In the past, some of the "niche clubs" have had small meetings at the NEC convention -- I've been able to sit in on meetings of the AGA, SNEKA (southern new england killie association), and NELA (northeast livebearers assoc.). I'm not sure if they are doing that this year, but I've seen some great planted presentations from Karen Randall at the NEC over the years, and gotten many rare killies right from the breeder at the SNEKA meetings.
