Moms Panelist Anna offers some great advice for guests dealing with diabetes at Disney World
HERE. There is a Guest Assistance card that you can get from the Guest Relations offices at the theme parks. Depending on the level of card you are offered, you may be able to bypass some of the longer lines in the parks.
If your family members have eating issues related to their diabetes you should know that special diets can be accommodated at Walt Disney World. There is
an entire department at Disney Dining dedicated to helping guests with
food allergies, other medical issues, and
religious-based food requirements. Just send an email describing
your situation (at least 14 days in advance of your trip) to
SpecialDiets@DisneyWorld.com.
A cast member will get back to you with the information you need to
make sure that your family has a safe, and delicious, visit to WDW.
A great resource for you is a book called PassPorter's Open Mouse for
Walt Disney World and the Disney Cruise Line. This is available through amazon.com. Open Mouse gives incredibly detailed information for Disney
guests with any sort of challenge. I would recommend a purchase of this book even from overseas.
Additionally, you can go to allearsnet.com. Click on the "search" button and search
on the term "diabetes." There are some extensive articles there that
give wonderful information on how parents of diabetic children have
coped with the challenges posed by a Disney vacation. I'm sure you will
find some help there.
