I fly home on monday, so sunday is still a full day for me. The convention closes down, but will still be there. Last time, my friends and I ended up seeing a movie. If there were convention stuff, I'd do it, even if it were just a dead dog open gaming room. Just give us late travelers a room, and make sure the info gets out about where it is. After all, we have our purchases to play with :) If nothing else, we could take over the mcdonalds and subway at the hyatt. They have been pretty friendly in the past, and unlike the mall, they stay open sunday evening. We could also coordinate some meetups here on the forum, but I know that I tend not to look at the computer until stuff starts to drag on sunday, and at that point it's too late. I guess I just don't want it to end, not till the plane takes off, and even then, I will be reading a gaming book :)
I don't like flying in the afternoon. As the day wears on, the delays pile up, and there's less space to recover from a problem. I want to wake up, check out, and go home. But I don't want to miss sunday at the convention. If I fly home sunday, gencon turns into the best three days in gaming. Oh, also, if I fly in the afternoon, I'm stuck lugging all my high quality stuff around from checkout time till I hit the airport. That's not fun.
edit: I arrive on wed too. But wed seems to work out ok. The hyatt lobby always seems to have some tables and some people playing games on wed.
