When booking my up coming cruise this past month, I did ask the rep at CCL about the Loyalty program and she said they were soliciting feed backs from people but no decision has been made.
This is still posted on my profile on CCL.
At Carnival, it is a pleasure to welcome you aboard again, and again. In fact -- starting with your second Carnival sailing -- you will become a Gold Member of our Past Guest Recognition program. With only your tenth sailing -- you'll qualify for the benefits of a Platinum member. And with Carnival's new Milestone program, you'll receive shipboard credit representing 25, 50, 75 and even 100% of your 25th, 50th, 75th and 100th sailing respectively. It's our way of saying "It's good to see you again."
The cruise we are taking in Feb will be our 9th cruise with CCL.
