Agree to disagree. That 15 night cruise may be the beginning of 50 seven night cruises. The 5 three night cruises may be all the cruises that person will ever do.Not exactly. Loyalty is not about how much money you spend its about your devotion to the brand and how much you keep coming back. If I go on one 15 night cruise I have been on the same number of nights as someone who went on 5 three nights cruises. But the other person who has chosen DCL 5 times as their vacation choice has been a more loyal customer.
However, a loyalty program is a loyalty program no matter how you do it. My point was it can be a loyalty program whether or not it is made up of number of cruises or number of days. Its a loyalty program. Yes, its about devotion but it could be either and still qualify. You can be loyal either way. Heck, you could make the loyalty program all about cabin catagories. Its still a loyalty program. They get to choose, we get to follow.
