I went on the Florida trip in November last year, there were some cloudy days and some very hot days, a mixture really, I don't like it too hot so it was the best time for me to go. I would recommend you take a couple of jumpers or light jackets as well as your usual summer clothes. As regards to other things to do, like Cindy said there is very little free time as the tour is pretty full on. There are a couple of days you will have some free time, which some people just wanted to have a rest and relax, but the tour guide will always give you some options that you can do by yourself or with others on the trip if you wish. I went to the theatre of the sea on my free day in Islamorada, they have dolphins (which you have the option to swim with) sea lions and lots of other animals, it was a very enjoyable way to spend some time. Some of the others went fishing or diving or kayaking, so there are lots of choices. You will have a great time, it was my 1st trip with JY and my first time in USA, I absolutely loved it, really great bunch of people. I'm jealous, I wish I was going again this November. If there's anything else you'd like to know just ask. All the best Angela.
