Lots of excellent ideas and solutions. More mats and another gym is the main one. Rose Hill is a great facility and central location.

4 to 6 mats and another gym would cut it down to a 7 or 8 hour tournament. May not even need to be 2 days.

More than extra mats and another gym are needed to pull it off though: they need neighbors to step up with the mats, help to run tables, more refs. . and the biggest thing. . . help with clean-up at the end.
