There are generally NOT rodeos in Houston on a daily basis. The Houston Rodeo and Livestock Show,
https://www.rodeohouston.com/, held in February/March, is a large annual rodeo that also includes A, B, and C-list entertainment (depending upon the particular day and your musical tastes).
There aren't really historic plantation homes directly off of I-10, the major highway that runs East-West from Houston, Texas to Jacksonville, Florida.
New Orleans is an interesting city with lots of history and music. While there is great music daily (especially a style called "New Orleans Jazz"), there is sn annual festival called "JazzFest" that runs for two weekends in April. It is very popular and can affect hotel availability. One weekend has better performers than the other. You need to buy tickets a long time in advance. I don't know if riverboat rides a la Tom Sawyer/Mark Twain have returned.
As the Pp noted, to see things of interest. one usia needs to detour off of I-10. There are some nice beach towns like Destin, Florida and popular beaches like Gulf Shore, Alabama.
At Tallahasee, you can visit the capitol of the State of Florida. It is a semi-ornate building. I grew up in Florida and still respect the state. I don't think I would build a vacation with the capitol as a highlight, but more like an "added feature."
The drive is at least 14 hours of riding in a car, if one is strictly attempting to make time.
You probably would be better off taking some day trips off Disney property and going to some of Florida's springs, going to Saint Augustine, and. using the Brightline Train for a quick trip from Orlando to Miami.
