They do not leave me glucometer in the Aquapark

Hello, I am a little confused indignantly I want to go to Aquapark this summer, and seen videos of people with diabetes, who put their glucometers in waterproof bags.
I sent an email to see if I can throw myself through the slides with my bag inside the swimsuit and glucometer, if you have to wait a row and give it a descent .. (it is for my girl).
And they answer me no, that I cannot carry anything on top, when there are a thousand videos on YouTube of recordings with aquatic cameras and selfie sticks.
You have done in the Aquapark?

When you throw yourself through security slides they do not usually let anything take, in part it is logical, because you can take a turn and fly.The theme that you comment on the ranks A decrease does not suddenly occur, seeing the trend could solve this matter.Much encouragement !!!
