Hi Marise,
Welcome to the Moms Panel! You've come to the right place to have all of your planning questions answered!
What is great about a Disney Cruise is that that just about everything is included! Once onboard, all of your meals are included, snacks, room service, and drinks from the 24-hour self serve drink station. You will want to budget for any specialty drinks such as alcoholic beverages or specialty coffees. If you would like to dine at Palo, the adult only fine dining restaurant a per person surcharge of $15 will apply.
All of the onboard activities and entertainment are included, including the broadway-style evening shows, deck parties, game shows and movies - however a few things onboard that are an additional fee include: spa treatments, hair braiding, arcade games, bingo cards, internet service and phone calls.
As for Castaway Cay, any of the
shore excursions (such as
parasailing and
Castaway Ray's Stingray Adventure) and bike, snorkel and float rentals are additional. Lunch is included while visiting the island.
You will also need to budget for transfer service to/from the port (currently $69 per person round trip), as well as gratuities (about $12 per guest per night).
I hope this helps - happy planning!
