It is probably too early in your daughters diabetes adventure but something to consider for the future if you are a regular visitor to theme parks.
Apparently, if you have an insulin pump, you and one companion can jump to the front of any roller coaster queues. Your diabetes team should be able to provide a letter for you as a queue jump pass.
I have not tried it myself but there aren't too many bonuses to having diabetes so, if I was a fan, I would be making the most of it.
