Well, the usual, Key West, Everglades, Venice, etc are nice. For a laugh, you must fly into the major airports, Tampa Intl [TPA], Orlando [MCO], Sanford, Fort Lauderdale Intl etc, they're free of charge for those who dare! Superb fun to mix with the large airliners, plenty photo-opps, and it's a good challenge, trying to manage perfect RT. If you so much as start to mess up then fear not, they'll notice before you do, and tell you
I once did a night-time touch-and-go at MCO, slight pause on the approach frequency when i asked, but they couldn't think of a reason why not and were very helpful. There was no wind so we got vectored in head-on with a heavy jet making an approach to the same bit of tarmac (they landed first and vacated the runway, not that there wasn't room for both of us, at 12,000ft long!). On the climb out I started to turn, intent on buzzing the terminal buildings but, sharp as ever, Tower came on and said to maintain runway heading for a bit longer
PS keep the airport taxiway diagrams handy!
