I did book it already and i already paid for both my plane ticket and the transportation because i assumed they would give me some information on it at that point and i havent received any, thats why i am on here asking.
When you land go to Baggage Pickup and get your bags, then look around for a Carnival Rep with a big sign that says Carnival Cruises or something like that. Some airports have a desk for this, I am not sure at either Houston airport.
When you return from the cruise, after you get your bags and go through customs, follow the signs for Carnival transportation to your specific airport. There will be people there to direct you.
My degree of sarcasm depends on your degree of stupidity!
