Hey SnoopGirl, There are not any scheduled at this time. They will have one shortly going by the past history. If I get a heads up, I will be glad to post.
On the email, it is good to register with Carnival no matter who you book with. They started a "Welcome Home Offer". If you book within 60 days of your last cruise, you can get $50 off your next cruise for Category 4A and above. They will email you the discount.
Just thought I would pass that along.
