Quoted from dfsays:
It sounds awesome AND I could tour the Stern plant.
PLUS, there's a gameroom open all night.
It's this worth the trip from mid-Michigan?
For me, and others, the key to having fun at Expo, is being with people. You will get the most out of Expo by meeting up with other pinheads, spending time with them, and possibly having meals with them.
There are lots of things to do at Expo, and machines to play, but that is only a part of the experiance. On a cost per game play, this may not work out, if that is what you are looking for.
I would caution you, that others who travel alone, eat alone, and play alone, do not give reports of a good time.
I have had the best of times at Expo for the last 7 years, and my only regret, was not going in the years before (when I first entered the hobby)
Hope to see you there.
Oh, and if you want to experiance Expo on a higher level, take a game, and meet up with the guys in the freeplay area who bring games too.
