Ahoy Gary!
Welcome to the Moms Panel and congratulations on your upcoming Disney Fantasy cruise! I've been fortunate to sail on this vessel a few times, and it is absolutely stunning! One area you will love is Senses Spa and Salon! This tranquil area is the perfect place to visit for some much deserved pampering and relaxation! Pricing can be found online in the
Senses Spa Treatment section along with the duration of the treatment and a brief description. On the first afternoon of your vacation, you can stop by the spa for an Open House to tour the facility. There will be raffle so you may be the lucky one to win a free service on your sailing!
The upscale dinner with a family you saw was most likely formal or semi-formal night. Disney Cruise Line suggests either a tux, suit, or sports coat, tie and slacks for the guys and a cocktail or full-length gown for ladies. I'm not sure the ages of your children, but I would suggest their nicest outfits for those evenings.
You won't need to bring a lot of cash since the ship is cash-less, but I do suggest bringing some. Cash tips are needed for the porters at the terminal, room service on the ship, and tips for tour operators. You may also want some for souvenirs in the ports of call.
I hope my answers are helpful, Gary! As you think of more questions, please write back!
Have a magical day!
Nancy
