Just a thought--since the college visits are more geared for fun versus actually picking that particular college, consider expanding what you see in the Boston area. There are a ton of colleges around, with a wide variety of offerings--big, small, specialized, urban, and so forth. Use it as a way to see what style of college might be the best fit for her, either now or down the road, if she finishes a two-year program and wants to go on. Plus--Boston! What's not to love? Visit the Science Museum or take a Duck Boat tour or see the Aquarium.
My oldest went to Boston University, and she loved the big, bustling nature of the city as well as the college--you really can't separate the two. Others would be completely miserable there, as there's no escaping the urban jungle. OTOH, we also toured UMASS-Amherst--we lived in NH at the time, I wanted her to at least LOOK at a state school, she wouldn't consider UNH, so UMASS it was. Well, UMASS is a large, bustling campus...set in the middle of a corn field. Literally--they invite you to go to the top of their library for the view, and all you saw was the campus...and cornfields! Ironically, DD is currently dating a young man who graduated from UMASS-Amherst--he seems to be doing fine for himself.
For your DD, she might feel more comfortable seeing a smaller, more contained campus, so that she can know that they're out there, and might be a good fit for her. There are commuter colleges, colleges that roll up the sidewalks on weekends, practically, and colleges that are inseparable from the community around them.
My older son has Asperger's--he's currently attending the local community college, and will transfer to the local branch of State U this fall. We're trying to ease the transition for him from one to the other--luckily, both are an easy driving distance, with public transportation also available. He has zero interest in looking at any other college choices, which we're fine with.
