Carnival offers a cruise deals and promotions page on its website. The links from most coupon code websites, such as Deals Plus, Coupon Cabin and Retail Me Not, lead to the deals' page on Carnival's website. Additional cruise deals can be found on travel booking websites, such as Priceline.com.
On its deals page, Carnival features deals by destination and booking time. Deals from Carnival vary, but customers can expect to find percentage discounts and free upgrade offers. In order to keep customers up to date on deals, Carnival offers an email newsletter subscription.
Certain categories of customers are eligible for discounts. Carnival VIFP Club members receive special discounts, such as a two category room upgrade. Active and retired members of the United States military and Canada National Defense are able to obtain a special military discount. In order to receive a military discount, proof of service is required shortly after booking a cruise.
As of 2015, Carnival offers a lowest price guarantee on all publicly available, advertised cruise rates. Customers have 48 hours from the time of booking to find a lower rate. In the event of a lower rate, Carnival issues an on-board credit worth 110 percent of the difference. A claim can be filed on its website.
