Well as the same "Senior Carnival Employee" that Dwayne got the original information from noted, an official press release is probably not in the near future. This was merely a survey type email to get a feel for what people thought. They are not close to making any changes yet this email survey did nothing more than stir up trouble by making people think they were changing things without any more information to go on. That makes people panic.
It was clearly stated that those that were already Platinum or above would be grandfathered in. But that is no comfort to someone who is on their 9th cruise (of say 4 or 5 day lengths) when the program changes (like my daughters who will be taken their 9th 7 day cruise this November)
