I've heard the Magic number was 10. But it all depends on who writes the checks. I would imagine 8 to 10 wouldn't too much of a stretch. It all comes down to who can come up with the best routes and be cost effieicent. I have nothing against
Galveston but this time of year, as an example, the number of times the port is closed due to weather almost doesn't seem worth it in comp that
DCL has to pay out. I watch John Heald on FB (Carnivals Brand Ambassador) and it seems almost weekly a ship or ships can't get in or out due to weather.
