So when you're viewing one of the cruise planner categories, say Beverages, your website URL looks like this https://www.royalcaribbean.com/account/cruise-planner/category/beverage?bookingId=000000000&shipCode=AD&sailDate=20230000
You see the word "beverage" in bold. Just change that to "packages"
So google tells me this is something Celebrity offers.
Watch this turn out to be a glitch.
