Go to AB because it's local and I love their programming, but I'm getting frustrated with security and the Pru. (Able to deal with young folk pretty well.) As for it moving to BCEC, staff claims that it wouldn't work with how they run the con.
Yeah I haven't hit up CTcon in a few years because they overcharge their badges, young crowd, no places to eat, and so much theft.
Portcon is good for parties/socializing but there is still a prominent young crowd. Don't do Animaine. It's a staff circle jerk, and in a tiny hotel.
