My son is autistic and has sensory issues especially with loud noises. We are taking our first family trip to US/IOA and I read on the forum about bags needing to go in lockers so things don't fly around, but I was wondering if anyone had any experience with wearing ear cups to reduce the noise on the ride. He loves Harry Potter and I would hate for him to miss out because they would not let him wear the ear cups. In case you are wondering, he won't wear ear plugs so this is really the only option (trust me we tried everything.) Thanks.
