I've booked my first cruise on Royal Caribbean and am very excited. The cruise isn't until December 2021 on the revamped Navigator of the Seas, for a 7 day sailing. Check in still isn't available but I wanted to get the Unlimited Dining Package as soon as I can. When I go to the website and try to use the cruise planner to pre-purchase the Unlimited Dining package I find two packages available. One is $87.00 and the other is $182.00. The text on both packages is identical, at least I can't see a difference. Can someone explain the difference? I tried calling Royal Caribbean to explain it to me but they seemed to misunderstand what I was asking. I know there are options for one restaurant, multiple dinners, etc.. I want the Unlimited Dining package for the entire cruise.
