With the new update instructing passengers to proceed to Mobile starting on August 14th., the parking will probably get stretched to the limits. The port is used to accommodating 1,452 passengers, now it will be 3,504. Think of all the extra manpower and coordination being put in to this. I bet Carnival has relocated the NOLA staff to Mobile, and they are staying in hotels during this.
Here is a link to the update.
