Here I am!
The USAF museum is great and as PP mentioned, the Presidential Hanger is great, but spots fill early for the buses, so sign up early in the day. We have never had to take the bus because DH works at the base, so we have always driven our own car to that particular hangar. It is a short drive, though, so you shouldn't be on the bus very long. It would take one day tops. There are lots of restaurants near the base, too. Fairfield Commons Mall area is what you would search to find those. That area is known as Beavercreek, OH.
As for other things to do, there is a University of Dayton basketball game on the 10th, and those are always fun. I could potentially get you some free tickets if you are interested in that. Also, the Cincinnati Premium outlets are between Dayton and Cincy (closer to Dayton) on I-75 and they have great stores, including a Disney Outlet Store (which I spend way too much money at
). The Dayton Art Institute might have something your kids would like, and if you want to hit Cincinnati, they have a great Museum Center that has 4 or 5 museums built into one large building. There is also an IKEA 20 miles south of the outlet mall that is a great place to go to (I spend too much money there, too!
)
If you come across something you have a question about, do not hesitate to ask!
ETA: The Cincy Zoo is nice, but I would not bother with the Newport Aquarium. It is very small and for older kids, it would likely be boring. Another great shopping area is the Kenwood Mall. It is down towards Cincy off of I-71. Very easy to get to taking I-75 to I-275, though. It is a very big mall (like huge!). They have a newly designed Disney Store, too. Oh and there is a shopping center not far from WPAFB called The Greene. I can't believe I didn't think of that earlier! It is very nice as well. It is kinda like it's own little city of shops. It is right off of I-675. I seriously cannot believe I left out The Greene. Duh me!
