Hi Natalie, welcome aboard! Your family is going to absolutely adore the Fantasy and all of the activities and events going on onboard!
Movies will be shown continuously throughout your cruise in the
Buena Vista Theatre. They typically start with the first show around 8:30 a.m., running through late night, some even being shown in 3D. If you call Disney Cruise Line about a week before you set sail they will be able to tell you which movies to expect. I was on the Magic last week and they were showing Frankenweenie, Tangled, Brave, Lincoln, Wreck-It Ralph, and The Avengers, among many others.
On the Fantasy, you're in for a real treat with their Broadway style shows almost every evening. Two of the best shows on the ship that are not to be missed are
Disney's Aladdin and
Disney's Believe. Each show in the Walt Disney Theatre is shown at least twice that evening, at 6:30 p.m. and 8:30 p.m., as well as the occasional matinee around either 2:00 or 4:00 p.m.
Be sure to check your Personal Navigator each day, as that is where the day's events and schedules will be listed. I promise you'll never lack for something fun to do!
Have a great cruise, Natalie!
