Ahoy Kerry-Anne!
  Thanks for visiting us at the Moms Panel with your  question. I'm excited to hear about your cruise next year on the 
Disney Fantasy - it's such a beautiful ship!  
  I'm glad you're planning to book some time for your 15-month-old at 
It's A Small World Nursery. 
  It's  such a wonderful facility, and the well-trained staff will take great care of your little buccaneer! You are more than welcome to  schedule time in the nursery while you venture out for a 
Port Adventure.  I would advise you to drop him off about 15 minutes before the  scheduled meeting time for your adventure. Make sure to let the nursery  workers know that you'll be leaving the ship, and your expected time to  arrive back.   
  If your child will be in the nursery during meal time, you'll need to provide snacks and food for him. Fruit, cereal or dry snacks are great items to leave with your child, and can be picked up at 
Cabanas buffet. You can also order something from Room Service to drop off with him. Make sure not to include any nut products, as they are not allowed.   
  If you have any questions or concerns about leaving him in the nursery, I encourage you to speak with the nursery workers on your first afternoon onboard, during Open House. They'll be more than happy to answer any questions you have, and to assure you that he will be well taken care of while in their care!   
  Hope this helps! Please let us know if you have more questions as you plan your magical vacation.
