Hi, just off the 5 night Wonder yesterday. The link to the Navigators is pretty much Identical to what I remember reading. In Cozumel, we went to Paradise Beach. Kids ( 15, 13,11, 8 and 7) and adults all loved it. Rented wave runners (60. per 1/2 hour) and went parasailing (45. per person). Taxi rates were posted 15. for 4. 30 for 6-8 people. No more than 8 people allowec in taxi.
We drove down from WDW. We paid all the tolls in cash. We did not get a sun pass. Rented a car and dropped it off at Miami airport. Learn from our mistake, and fill up a few exits away from airport. We wound up paying 4.79 a gallon at the gas station next to the airport. The rental companies offer free shuttles, but they do wait for the buses to fill up. The ride itself is not long.
Let me know if you have any other questions. Enjoy your trip.
