Hi there, Hannah! Welcome to planDisney. I'm so glad you stopped by with your question ahead of your sailing on the beautiful Disney Wish.
I'd be happy to help you feel prepared for a delightful cruise full of delicious dining! The Wish has some of my favorite quick-service dining options in the fleet. To begin, I recommend that you review the Special Dietary Request page on the Disney Cruise Line website. Please share your dietary needs with Disney Cruise Line through the Special Requests application under My Reservations when signed into your Disney Account on the Disney Cruise Line website.
You may wish to fill out a Special Services Form if your allergies are severe. On the day you embark on your cruise, you can visit the Onboard Dining Session to speak with a member of the dining team regarding any questions or concerns you may have. You will need to notify the Crew Members at the dining venues (including quick-service or room service) of your allergies so that they can properly assist you. If necessary, you may wish to dine in the full-service restaurants for breakfast and lunch. Depending on your allergies and needs, you can discuss what options are available to you in person with a Crew Member, and they can advise you as to what is best. In some cases, you might be advised to place an order for the next day's meals at dinner.
When dining at Castaway Cay, you'll find a variety of fresh options to choose from. Food offerings include chicken, ribs, burgers (beef or boca vegetarian), hotdogs, grilled fish, corn on the cob, various fruits and salads, cookies, and desserts. Allergy-friendly food options are available at Cookies Too BBQ. Please speak with your dining team the night before you visit Castaway Cay to discuss allergy-friendly options.
If you are looking for milk alternatives while you sail, you may request Oat Milk, Lactose-Free Milk, Soy Milk, Rice Milk, and Plain Almond Milk through the full-service restaurants onboard. Please speak with the head server to make your request. These options are subject to change and availability.
I hope that covers it, Hannah! If sweet potato fries are something that you enjoy, you can request them at Mickey's Smokestack Barbecue. That's my favorite poolside treat to eat while watching a movie on the top deck.
Have a wonderful sailing!
