As long as it doesn't get too big I'm cool with it.
I used to go to tons of cons as they were exploding in size and number in the 90s/00s. I quit mostly because they all got to be so huge that you have to fight crowds, not just at the con, but MILES from the con because that's how many people come to some of these things now. Yeah they have big guests, but now you have to win a lottery for the right to stand in line for three hours to see them and pay maybe $80 for their signature.
More of everything is good, but be careful because for every new guy that brings a cool rare pin there are going to be 7 pickpockets, 3 pedophiles, 2 crooked vendors, and 47 cosplay dirtbags sleeping in the lobby restroom because they got kicked out of the room they were all sharing.
I'll be there, btw, with a three year old. I've only been there once but it was fantastic.
