My son had the Minimed Revel Insulin Pump and CGM. We went to Disney in August for the 1st time flying and to Disney with the pump. We had a letter from his endo's office saying no airport scanners and no xray and medtronic said the same thing when I called. So he had to be patted down for the airplane. No issues with any ride and we did them all.
As for Disney he had his pump on 24/7 except for the swimming pools and taking a shower. When swimming even at home all summer, we test every hour, cover any carbs, feed for lows, and let higher numbers go, because the exercise evens it all out in the end.
As for carb counting at Disney, they do not provide the numbers, but since he basically eats the same thing all of the time, grilled cheese, pizza, hot dogs, fries, etc and always diet drinks, milk or water, never juice (except for lows), I just guessed based on what I would cover at home. All of the exercise of walking in the parks helped and we had some pretty decent numbers all week.
As for packing stuff for the trip, I packed at least double if not more of what he would normally need. I took Lantus and Syringes in case anything happened to the pump. I also took an extra meter and strips in case anything happened there. I took ketone strips, glucagon, tegaderm, a whole box of sure t sites for the pump, extra batteries and for insulin on the plane, I had it in a smaller cooler bag with a frozen water bottle, that worked to keep the insulin cold for about 18 hours. I also prefilled some insulin cartridges before we went to take from a different insulin bottle and then took a brand new bottle, that way different lot numbers in case of any problems. I also took written prescriptions for insluin from his endo.
I did over pack and brought a lot home, but I did not have to worry all week about anything supply wise.
In the parks he carried a small bag, the same one he does at home. It goes across his body so he would not lose it and in it we had an extra site or two, alcohol wipes, meter, strips, and glucagon, along with some fruit snacks and glucose tablets. He wore it on every ride and never had to be apart from his bag. That way if something happened that we were separated he had his bag. (he was 10 yrs old)
Hope this helps! Have a great trip!!!!
