I've read that you need to be 42 inches to ride the aquaduck with a parent and that its strictly enforced. Has anyone had an experience with a "very close to 42 inch but just not quite there yet" child being allowed to ride with a parent? My youngest will be 3 weeks shy of her 5th bday when we sail and as of today is about 40.5 inches. Not sure if she'll grow 1.5 inches by the time we sail in late june but she'll probably be close. She'll be crushed if she can't ride but her older sister can.
