Yes, we chose to go to Key West at the last minute. Since we only had about 4 days we chose to go somewhere that we felt didn't have a whole lot of sightseeing since that is what we like to do. We would have liked to have had a whole day at the beach just to lay around. But we spent our time at the Pirate Festival which was very interesting, with some interesting characters. We also toured Hemingway's house, rode the trolley around town to learn about the history of Key West, went out to eat a couple of times - one you must go to when you go to key West and that's the Conch Republic restauarant - I found it to be excellent! We took a fun speed boat ride too. And of course watched the Sunset from the famous Mallory Square and watched a couple of street performers there.
We missed all the kids, but we do enjoy our time together.
