I'm hoping someone out there can help. We're planning our first cruise with our kids for March break 2011. We got a great deal on airfare flying into Punta Gorda, Fl. I understand (from mapquest) that it's about a 3 hr drive from Punta Gorda to Miami. We are arriving a few days early, just to be sure. BUT .... our cruise (Carnival Liberty) arrives in port at 8am, on the day we leave. Will we have enough time to get our rental car and drive to Punta Gorda? Any suggestions would be welcome. Thanks!
