Hi, Kelly!
Congratulations on your cruise this summer aboard the beautiful Disney Wonder to Alaska! With Disney Cruise Line embarking on its first Alaskan itinerary next week -- on board entertainment plans and schedules are still being finalized. Rest assured knowing that the cast and crew are going to make this a trip of a lifetime for you and yours!
There are 3 live, Broadway-style shows presented on the Disney Wonder -- Disney Dreams: An Enchanted Classic, The Golden Mickeys and Toy Story: The Musical. Once you are on board, you can take a look at your Personal Navigator to verify which nights will feature each show. Plus, your dining/show tickets will be in your stateroom also to indicate your dining and show seating times.
On a 7-night itinerary, there is a suggested formal (tuxedos/suits and evening gowns) night and semi-formal night (suits and cocktail dresses). Again, your Personal Navigator will direct you on suggested dinner attire as well as where you can go for a casual bite should you not be in the mood to get all dolled up. I hope that helps you plan.
Have a wonderful day and a magical vacation. Bon voyage!
Andi
