It’s still hot in Florida in October. Really, really hot, and freaking humid!
We spent a few days in Key West, specifically Sunset Key (and had to take a boat back and forth to the hotel!), in October 2009. While the scenery is gorgeous, it’s more of a party town geared toward the younger folk. You know, the Duval Crawl and all. But it was very relaxing and you can’t beat the sunsets there!
