Just got off the Odyssey on friday (Christmas sailing). We LOVED the WJ (and many other things on the Ody) but thought it was just good design on RCI's part across its fleet!? We're thinking of Wonder of the Seas next (to experience the BIG OASIS class, again, only other sailing was Allure 11 years ago and memories are fading 😁).
Edit: Just to add more, we thought the food on the cruise was great and we liked the fact that there was plenty of seating in the WJ, there were tables on each side all the way to the back and wrapped around and there's a food counter/outlet at the stern. Our Christmas cruise was supposed to have the highest passenger count 4800 ("beating the previous record holder by 5 passengers" was what we heard at Captain's Corner), yet we never had an issue looking for a place to sit, including debarkation morning at 8am haha. There were many choices, plus specialties stations such as Gluten Free, Vegetarian and Vegan (we are none of those but have friends who are). Just wish the WJ was open later than 9pm but there are other options : Cafe Promenade has pastries and sandwiches, Sorrento's has pizza, and Playmakers ($) has many pub food options, to name a few.
