Go to tacogirl.com and look for the Tropic Air 10% discount. This works out great. Just print out your confirmation and present it at the Tropic Air desk. Pay for your flight (less the 10% discount) and off you go! I give myself about 45 minutes after landing at the International Airport to catch a flight to the island. If for some reason you are held up at Customs - don't sweat it, Tropic has planes flying to San Pedro all day long. Airlines want you to be at the airport 2 hours before your return flight to the States. You might consider waiting until you are on the island to decide if you will need a golf cart for your entire trip. There should be plenty of carts available in July if you want to go explore the "far" north and south of the island. The water taxi gets you north and south easily and is lots cheaper. They have a weekly pass that might help you out. Have a great time!
