See this is what you would know if you had ever been involved in hosting a tournament. There is NO planning because all of us are limited on dates that we can access facilities. I wish it was as simple as those of you that have never hosted a tournament, make it out to be. It simply isn't!
As to your "full mats", maybe it is you who needs to steer clear of the larger tournaments because there are those out there already offering that. When you exceed the capacity of your facility that is when you have 14U wrestling on half mats and 10U wrestling on quarter mats. Believe it or not, there are tournaments out there right now wrestling on full mats for most age groups.
