DTS - Destin FL up in the panhandle. Grab the courtesy car and get lunch at the Back Porch or Fudpuckers.
SGJ - St. Augustine south of Jacksonville. Great place to eat on the airport, watch all the aerobatic shennanigans, visit the Grumman facilities.
TPF - Peter O Knight. Five minutes to the middle of downtown Tampa, all kinds of stuff to do there
APF - Naples. Get the courtesy car, go to Michlebobs BBQ, get the feast for two. Make sure you don't top off with gas because you'll be fatter and way over gross when you get done eating.
EYW - Key West. Need I say more? Catch a cab to the square, pick a place to eat. Recommend Schooners or the Conch Republic.
