The quick and dirty from my stint in MIA:
-Get a crash pad. Budget $300. Hotels will run $100-$150/night.
-Uber from MIA to pad will be about $8 each way. Uber from pad to FLL is about $50. PBI will cost you $100. Budget another $300 in Uber.
-You will not fly every day. Don’t call scheduling and beg for a trip; you’re in the big leagues now. Enjoy your daily walks and bike rides. Budget $0.
