Moved to Florida section for more coverage.
What are you looking to do/dive, there are plenty of options from springs, to hunting, to reefs, drifts, fossils, wrecks both deep and shallow, near shore, way offshore and much more. Its about 2-3 hours for the springs and cave country, 2.5 to Jupiter/WPB, 3-3.5 for Ft Lauderdale/Hollywood, 1.5-2 to Venice and then more for other parts of the west coast. If you want to dive deeper it might be better to try the east coast as it gets deeper quicker and there are some outfits that do more tech dives - however that is usually during the week.
I know i am busy this coming weekend and off for medical leave for the next few weekends so i cant show anyone around as such. Welcome to SB and the US, you came to FL at the worst time - summer/hurricane season, it gets better through the autumn and "winter" time
