can always develop post-op complications that require weekly or more office visits that you will certainly being paying for out of pocket.. Do you have a plan B to see someone locally should this occur in your situation? If not, consider staying home. But if you're dead set on going to Miami, your surgeon should be the one instructing you on just how long you should stay down there.
I cannot speak for your plastic surgeon in Florida, Only He/She can tell you how long you should plan on staying as they are the one who has evaluated you and know what they plan to do for you. I can only tell you that when patients have flown to my office in Maryland from around the country and around the world for Tummy Tucks, I recommend that they spend an absolute minimum of 2 weeks in town if they are coming from neighboring states and preferably 3-4 weeks if they are flying in from far away. One reason in particular is because your risk of having a blood clot/ pulmonary embolus is elevated for approximately 1 month after surgery, especially abdominoplasty.
