We are traveling with another family in Oct. 2 of their 3 kids is under age 3. The older of the 2 will be turning 3 a month after our trip. Because he is a tall child etc for his age will WDW question his credibility & have us purchase a pass for him. What happens in this type of situation when entering the park turnstiles etc. He will more than likely be in a double stroller with the younger child.
