If considering just a convention center, it's hard to top what we have here in Las Vegas...
The Las Vegas Convention Center (LVCC), located adjacent to the Las Vegas Strip, encompasses approximately 3.2 million square feet with exhibit space of 2 million square feet and meeting space of nearly 250,000 square feet. The facility is one of the most modern and functional centers in the world - centrally located withing walking distance of 100,000 guest rooms.
Now if you could just convince the Visitors Authority and the hotel/casinos that 15,000 kids who don't gamble would somehow be a good thing for their businesses...and also convince the team's parents and school boards that Las Vegas doesn't have a lock on "sinful" behavior then you might be on to something
If you thought two alliances racing to tip the bridge in auto was exciting, wait until they play autonomous chicken on the center line. :D - Alpha Beta [more]
