Royal Caribbean has added a variety of casino tournaments to pre-book via its Cruise Planner website.
RoyalCaribbeanBlog reader Lorraine Steeves shared a screenshot of some of the options.
Options for blackjack, poker and slot tournaments now appear for some cruises. Once on the ship, you have to visit the Casino Cashier on Day 1 to register for the tournament.
Casino tournaments are offered on most cruises, but it has historically been something to sign up for exclusively once onboard.
Let us know: Will you prebook one of these tournaments? Tell us in the comments!
