Game Design tours/ Mueseums

I have a younger cousin who is severely autistic, and when talking to my uncle about him recently he told me he has become fascinated with the people who make games and the creative process behind it, to the point where he watches and memorizes the credits of the games he beats. That said, does anyone know of any companies in New England (they live in Maine) that offer studio tours or have community events, or are there any cool museums/places they could take him? Obviously they don't want to take him somewhere super loud and crowded like PAXeast, and the Museum of Play in NY looks cool but I've never been there.
