Actually, I went to one, and din't spend the whole day there, but that's because I went there for a small scale pokemon tournament, course after we got there, we were told if we'd done something, we could've gotten half off or something for the entrance fee. xD
Lol. You should stay next time! When we go to Otakon we try to spend as much time as possible before we get hungry around dinner time... Convention food is too pricey so we go elsewhere and usually call it a day.
Well there are some people who actually do that... Like if they want to go just for a music concert or something in the dealers room... But usually people go for the whole three days.... Me and my friend usually don't go on Sunday though because that's when we have to leave the room and such... So it would be a pain...
Honestly, the pokemon stuff was on Saturday, and Sunday only. So if I was to go for two out of three days would've been nice. They had a team tourny on Sunday, then the singles tourny on Saturday.
You could pay for one day, or pay for all three, and we just did the one day thing for multiple reasons, mostly, the first day was on a chool day, second, my other friend had to go back to where he lives on the third day, and finally, all of my good friends, are very big into christianity, so they always go to church when possible. I would never be able to talk any of them into going to any pokemon event instead of church. xD
