The problem with finding a place for chamionships (besides space for the pits) is that you need not just a big floor space but a big area of elevated viewing around it. In places like convention centers, this may me hard to come by. They are great for floor space but don't have any provisions for spectating.

The stadium where the AZ Diamondbacks play in Phoenix is really nice. It has a roof that closes over it. The fields would all fit on the baseball field and the pits could be in the large corridors underneath the stands all the way around the arena. The only problem would be lack of a concrete floor.
