Tallahassee has a football stadium bigger than Orlando. UWF plays its games in downtown Pensacola. If you don’t want college stadiums there are other large municipal stadiums that have the capacity, and I’ve seen the crowds which would fit in many high school stadiums easily. There are more hotels in the panhandle. We have basketball courts at FSU, UWF, NWFSC where they host a Thanksgiving weekend College tournament broadcast nationally. We have baseball stadiums at all those schools as well as in all the cities. There isn’t a single sport that could not be hosted in the panhandle at a venue equal to or better than a south Florida site. It could be done and should be done, at least for no other reason than to get people out of south Florida to show them another part of their state that isn’t like the rest of Florida. If a sport is hosted in Ft Myers then it should also be hosted in the panhandle the next year.
Football state Championships are actually in 2 cities this year (Tallahassee and Daytona). For 1A, the games being in Tallahassee should be a boone for the number of people attending (unless it is Pahokee).
As for the rest of the stuff, it all depends on if you have the space and your city is willing to pony up the costs to host it. I will state that if I was going to host any of these things, it would be Cross Country and Track. You have more teams, more individuals, more hotel beds filled up (due to how early the meets are), which all means more parents spending money.
And Arnold High School hosted Girls Weightlifting last year.
