Royal Caribbean announced just today that they have revamped the dining room choices in a significant upgrade project. Here is an excerpt from the press release:
"Catering to the increasing demand of heart-healthy, gluten-free and lactose-free options for guests, Royal Caribbean also has enlisted a registered and licensed dietitian and nutrition consultant to evaluate existing menus, create new offerings for guests with dietary restrictions, and shape the cruise line’s current gluten-free and lactose-free program into a more guest-friendly experience. All low calorie, gluten-free and lactose-free options will be clearly identified with respective menu icons as well as menu selections that can be modified to fit these requirements for guests. The updated menu format also includes a new vegetarian symbol, which is the official symbol of the European Vegetarian Union and considered the most widely used vegetarian symbol worldwide for easy recognition. In addition to the new menu designations, Royal Caribbean is rolling out new daily gluten-free bread offerings, available on request in all venues, including specialty restaurants."
I do suggest you contact your agent, if you use one, or Royal Caribbean directly to advise them that your booking now requires a gluten-free diet for your spouse.
