Actually that 110% thing is over a year old now that I think about it.
My understanding is the policy applies to all places where you can buy a cruise, even the Carnival website. A rule is a rule. They can't really allow you slack on the time deadline if you book with them, but not if you find a lower price on some other site, especially since Carnival did revise their booking rules on August 1st which restricts discounting or rebates by agents or other cruise sellers. In other words, it doesn't matter that you booked directly with Carnival.
Also - please don't use employee names in posts.
