Make sure you have the right medical CAA med for CAA Licence, FAA med for FAA licence (you mention FAA PPL and CAA IR) Cedar key is great, the Unicom is the local taxi, call in before landing and you will get a ride into town. Marathon down on the Keys is a good destination, anybody who hasn't had instrument training should be warned that when it's hazy, soon after take off, the blue sky and blue sea blend into one and it's time to rely on instruments. Suncoast Flying Services are a good friendly crowd and there is a good place to stay on Clearwater beach and so cheap, ask Denise at SFS for details. You can hire a twin if you have the ratings and you can show the flying club that you can fly it safely as with hiring any other aircraft. Daytona is an absolute must, close to glorious beaches and you will see the famous Daytona race track when on final to Daytona Airport. Ormond Beach airport is a stones throw away and the self service pums there have what was very reasonably priced fuel, it's self service and you'l need a credit card. Oh and Florida is best enjoyed November thru to April.
