Saw your old post about flight simulators in the DC area. Not sure if you're still interested but about an hour or so away is the Pautuxet River Naval Air Museum in St Mary's County. Visited there this past summer and they had 4 flight simulators where you sat in "actual" cockpits and controlled what you saw on a large flat screen on the wall in front of the cockpit. No motion but still pretty cool. Here's a link.

On the other hand, if you could get your dad to Mall of America in Minneapolis, I have a friend who operates these:
