Due to SWA and Sixt offering fully refundable reservations, why not? Now I can just monitor prices and see if I can do better. BTW, if you're going to rent a car at FLL airport, it's crazy how much cheaper Sixt is for a car rental than the big guys, like 50% cheaper.

Let's hope I'm canceling these reservations for a better bowl, but if not, I'm all set.
