The Fort Lauderdale Boat Show is a great time to look for yacht jobs in Florida. I used to arrive in Fort Lauderdale a few weeks before the start of the boat show. The Fort Lauderdale crew houses may be able to give you more information about the work situation there and when the best time to arrive is.
Even if you are not looking for yacht jobs, the boat show is an interesting time to be in Fort Lauderdale. You can walk the docks and look at yachts that are selling for several million dollars each (or even more).
