All major lines can accommodate special requests, but some lines have larger programs than others. SeaDream Yacht Club, for instance, is the only cruise line with an optional raw food menu. Regent Seven Seas Cruises and Oceania Cruises offer vegetarian dishes and a vegan menu with breakfast, lunch, and dinner, and even afternoon tea. Costa Cruises has a gluten-free menu in the main dining room for three meals a day, and on Carnival Cruise Line, you'll find gluten-free bread, baked goods, pizza, and even beer. Disney Cruise Line also does a great job meeting dietary needs for families.
