Ahoy Stephanie!
Welcome to the Moms Panel! On your formal and semi-formal night you will see a variety of dressy attire in the dining rooms. My recommendation is to avoid shorts and bathing suit attire and plan on wearing your nicest outfits that night and enjoy whichever restaurant is on your rotation that evening. If you don't feel comfortable with that suggestion, there are other options you might look into. Room service is available 24 hours a day and included in your cruise fare.
Cabanas, on Deck 11, is a more casual sit-down option for Guests not wishing to dine in the main dining rooms. Foods such as burgers, fries, chicken fingers, wraps, and hot dogs are served up at Flo's Cafe, a Cars themed eatery also on Deck 11. You will want to check your Personal Navigator, the daily cruise newsletter, for the operating hours for breakfast, lunch and dinner each day!
Thanks so much for stopping by with your question, Stephanie! I'm always happy to help so please keep me posted as you continue to plan!
Have a magical day!
Nancy
