Welcome aboard, Teddy!
I sailed on the Disney Magic last week and had the opportunity to meet with the director of Youth Activities. We discussed in detail how Disney counselors handle children with special needs. You'd be amazed at the training these counselors have and the different types of needs they deal with each day. They do their best to work with the parents individually to ensure that each child has the time of their lives in the clubs.
When you book your cruise, be sure to note on your reservation that your daughter has diabetes. You can give any other specific information at that time that would be helpful for the counselors to know. This way the counselors have this information before your daughter even arrives at the Club.
Once you are onboard, simply chat with one of the counselors before you drop your daughter off in the
Oceaneer's Club or Lab. You can let them know any additional information they might need. She is welcome to play on her own in the Club while you're off enjoying some adult time. You will have a Wave Phone, (like a cell phone that only works on the ship), so the counselors can call or text you if necessary or if your daughter is ready to leave.
You might not know that Disney has Open House hours in the Club and Lab, so parents can experience the fun with their kids. During these hours, parents must stay with the child to participate in activities. This might be a great way to give the club a first try with her, then see how comfortable you feel with leaving her during secured activities.
I promise that the counselors there will be more than happy to work with you and your daughter's needs to ensure she can easily and happily enjoy magical time there on her own.
Have fun planning and let me know if I can help with anything else, Teddy!
