I have type 2 and have been going to Disney for years with little problems
If you aren't going till Nov. you have plenty of time to get an eating plan together and see if your doctor wants you to count carbs or monitor your eating and sugar in different ways.
you will get used to your body and the "signals" for low or high swings.
I can still have a bite of goodie here and there- i have to be very careful and follow my meal plan.Like i can't eat TONS of the Potato casserole at Garden grilll or Pasta at Italy AND have bread..
All Ears has menu guides as well as the Dis so you can see what is good for you or not. and the Chefs are AWESOME about telling you things you can order etc..note on every ADR that you are Diabetic.
I have been "lectured" by WDW nurses many times on Diabetics need to drink 2 bottles of water per hour. some days the heat gets to me and we have to stroll and other days I can go full out hit every ride all day.
bit of news i learned recently in a diabetes class and was told not to do finger sticks in public. go to a first aid station so you can wash your hands in a clean enviroment. when i said something about Disney the nurse was like freaking out : do NOT stick in Public- there are more and more cases of people getting staph infections after A. Sticking yourself on the finger, B. Not washing hands & C. having what is considered now an open wound....
you grab a door handle or an item in a store and someone who has staph can send it to your open wound. the Nurse/instructor went on to tell us about her friend who lost body parts due to staph (mercer) she was disbetic and they felt the site started from a needle stick for testing.
go to a first aid station, wash hands, stick yourself and slap on a bandaid.
(the nurses at WDW LOVE to hand out bandaids- i carry my own and they are like -no here take one for later
I am sorry didn't mean to scare anyone - I am just really OCD about handwashing for Diabetics.
