According to a very recent Attractions Magazine article, Sesame Place in PA just announced new accommodations called Autism Days. On those days they will modify some rides and shows to be less loud/with reduced effects.
Thier general policy is to use the IBCCES card for those with disabilities. In the park, qualified guests are then granted 6 attraction passes, and/or 3 water attraction passes, to be used on 6 different rides or some repeats (repeating a ride = using one of the 6). Guests cannot use the passes at character greets or for shows. The passes are described as granting priority access via a special queue.
The pass is limited to a total of 4 guests, the passholder and 3 additional companions. As with other disability passes, the passholder must be one of the riders.
I've never been there, but it looks like they have a total of 15 rides, and 4 water slides (plus no wait wet options like a lazy river, splash areas, pool.) Looks like they have 3 shows and a parade.
The part I found interesting is the idea that the pass allows a specific number of uses per day.
