I booked one of the "free" cruises and they did charge the $20/day administration fee plus standard taxes. So $267 while online shows $1625 without drinks, plus gratuities due on both.
It was a 40 minute phone call, no single supplement, yes free drinks in the casino. I declined the free at sea promos with an upcharge so only took 75 minutes of internet and $50 credit per excursion. I also submitted the shareholder form online from which they added my OBC in three days.
