Disclaimer: I have NO experience working for a cruise line, so this is my observations only.
Reading that FAQ, I see a lot of well-worded roundabouts to the questions. "...in deference to our paying guests and in accordance with on board regulations" sounds suspiciously like "not gonna happen." I'm just paranoid but, I would find out more from a reliable source inside before I'd commit to that.
Free opinion, worth what you paid for it
