I have two 1-bedroom condos in Kissemmee (west of Disney) that sleep four each. It is a fifty minute drive from Tampa. $120 a night for at least 5 days.
I reserved them in hopes that my team would be there, but they are not because of the team you are playing. email me if you are interested.
It is a straight shot down Interstate 4. I made this trip for the World Series this year. Just think, you can sell the trip to your wife as a small vacation for the kids at Disney, while you visit Tampa.
