The casino dept put me in touch with a rep from Guest Services. NOT EZ air. I was able to book the flights I want. Still flexible flights although I had to pay for them in full. This is the thing to know about casino comped cruises. Cost of cabin is only thing left unpaid for casino services to take care of several weeks before sailing. Guest pays taxes ,port fees, transfers and air in full at time of booking. There is also $200pp nonrefundable deposit which becomes OBC when you board the ship. When all is said and done I guess it is still a good deal . Of course that is if there are no screwups.
It may be my imagination but it seems there are many more casino comped offers than ever.
Thanking anyone who can add their experience to this.
