Here's an idea. Why not take yourself and some of your gear to Florida on a train? I don't know where you need to go in Florida but Amtrak has a big train station in Tampa and other locations in Florida. The ride is more comfortable, scenic and, faster than a bus and cost less than flying. Plus you can get up walk around and visit the lounge and dining cars. If you're willing to spend more on a ticket you can get a private room which is nice.
You can take the first two checked bags for free and additional or oversize bags are $20 each. I don't know what the limit is but trains have plenty of luggage room and weight is not an issue.
