Dylan's Jimmy is surprisingly good at miniature golf. Like, really good. When asked, he just admits he "has a lot of free time."
Tenya will go, of course, and participate in a wide variety of family-fun activities. He may even be tempted into trying some of the American-fare at the concession.
Harry will go, after assessing the state of the vehicle transporting him, and declaring it to be old enough. He'll avoid the arcade, just to be safe, but might put up with a little bit of golf and food. He's mostly going stir crazy without cases or having to deal with supernatural bullshit since he arrived.
