I agree that the plane is actually a very safe way to travel to AC. If you choose to take the water taxi, you would probably need 2 cabs from the airport to accommodate that many people and luggage. The cab would take you to the water taxi terminal, and from there you would buy your tickets at about 25.00 US round trip, then wait for the next boat. The last boat from BZ city leaves at 5:30, and that means it will be dark for the 1.5 hour trip to AC. If your international flight arrives late in the day or is delayed, you could have difficulty catching the last water taxi. I do think the water taxi's are a good way to travel, but no question that flying is the best and probably the safest.
