The ultimate in Roadside America Tourist Traps.

You start to see the billboards advertising it as soon as you get a bit south of Washington DC. "Only 287 miles to South to the Border". The billboards are at once cute, funny, politically incorrect and culturally insensitive. But they are burned on my brain as part of my childhood.
Those signs used to be much more plentiful than they are now. I drove to Florida during college spring break and also drove a few times to Myrtle Beach in the 1980s. Back then, I'd say there were close to 200 SOB signs from DC to SC. These days it seems like it's only about 50. Some of them used to be REALLY insensitive and un-PC. But back then it was acceptable. Last fall there were only a few questionable ones still remaining.
If you like tacky, kitschy, cheesy schlock, like I do, SOB is worth a quick look. It's not like you have to drive out of the way to stop there.
Drove to Florida with three other guys during spring break in 1980. Straight thru with only gas/ bathroom breaks. Like many have mentioned, the trip there was full of anticipation, but the trip back was torture. After spending practically 24/7 together for a week in the same room, we were all on each others' nerves. I swore I'd NEVER drive to Florida again.
Didn't until DW and I delivered a car to our daughter in Orlando about five years ago. The ride there straight thru was surprisingly pleasant. We flew back.
Last fall we decided to drive again. Stopped in Raleigh, NC for two nights on the way there, but a marathon drive back. Even that ride back wasn't so bad. Still, it would have bern better to stop somewhere.
Planning a drive again to Orlando in late April or early May. This time we'll stop in both directions for a full day or two, not just overnight. Fortunately, we have the time to do this. DW detests flying anymore. After being able to bring all 274 bottles, jars, and tubes of lotions, creams, conditioners, and powders while driving, there's no way she'll go back to a little baggie while flying.
Still, if I was in OP's shoes, I'd fly, unless saving the $300 was vital.
