The Indy Convention Center
Back in October I got to tour the Indy Convention Center (I drive a truck and was picking up a load of convention materials to move from Indy to Atlanta GA). While I waited for my trailer to get loaded I wandered throughout the center, both in the areas everyone will get to see come GC, but also the "backstage" areas of the place. I have to say that place is something else.
First off, it's immense. There are 5 main exhibit halls, the smallest of which is twice the size of the exhibit hall used for the dealer's room in Milwalkee and all 5 of them can be combined into a single massive room with the floor area of 6 football fields if that is desired. This doesn't include the RCA dome which has a much larger operating floor space than is used for the Indianapolis Colts football games. Most (though not all) of the seats of that stadium can be removed if desired.
Second, it's got hotel space galore. 6 major chains have skyways that connect into the convention center, and there are 3 other hotels on neighboring blocks including the Best Western which is under construction but scheduled to be completed in June. There is ample parking - an entire football stadium's lot is next door with room for some 5000 cars (and hopefully one semi-truck).
Third, it is easy to find. You can see the RCA dome from I-70 as it moves past. If you fly in the airport is only 7 miles away.
Anyway, after my wanderings, I'm looking forward to the con being there. The explosion of available space will inevitably attract more gamers and the space makes it possible for Peter to drop the table price for dealers (since you could easily fit 3 times as many dealers into Indy as you could into Milwalkee, you could halve the table price and still come out ahead).
Oh well, I'll be there.
Although my post was actually a lame attenpt to get somebody to do my work for me, cause i'm lazy today.
