I received this email from Disney today. I was looking for more specific info. But, I received a generic answer. It does talk about dress code.
Thank you for your interest in a
Disney Cruise Line vacation!
I would be happy to assist you.
Dining attire varies by venue or theme night on your cruise. In general,
most meals are "Cruise Casual"-- jeans, khakis and capris are permitted;
however, we ask that Guests refrain from wearing shorts, swimwear or
tank tops in the dining rooms.
Below is the recommended attire for your cruise itinerary and is subject
to change:
On 8-night Bahamian cruises out of Galveston:
*Nights 1, 3, 4, 5, & 8: cruise casual
*Night 2: "formal night": formal wear for men: tuxedo or suit; for
women: gown or dress
*Night 6: pirate night with deck
cruise casual or bring your
best pirate outfit!
*Night 7: "semi-formal night": semi-formal wear for men: suit/jacket;
for women: dress or pantsuit
These requirements are not mandatory for the rotational dining
restaurants on the ship; however, in order to re-create a classic and
memorable dining experience for you and all our Guests, we recommend the
attire schedule that is planned for your upcoming cruise.
