Hi - we're cruising out of Miami for the first time next Feb, and our flight after disembarkation isn't until 6pm out of the Miami airport. Was thinking that my kids (boys ages 13 and 10) would enjoy going to the Everglades for gator sightings and doing an excursion on the boats through the marshes. Has anyone done this when they disembarked and still made it to the airport in time? Am hoping for recommendations of tour operators and especially if there are ones that pick up from the port and drop off at the airport. Also, if there are other suggestions of a great way to spend part of the day in Miami, that'd be greatly appreciated, too. Thanks!
