I have 3 cruises before the end of the year that stop in CocoCay.
Not one has "Diamond" (or anything) pricing.
I think that sticker shock has finally hit the cruising public, however.
Cabanas have been going for $1,300-ish for quite a while. Apparently, people are not biting. I see $699, $799. Still not cheap (I got one for $499 last year). Quite a price drop.
