Pondering a trip there, probably in the summer. I know--tourist season, but that's probably going to make the most sense.

Any advice on the best way to do this? Pair the trip with London or Paris? Any good way to see Bastogne or any other sites of interest? Looking like it'd be the wife and I. We're probably ambivalent about visiting London vs. Paris--maybe a slight lean to London but probably prefer to incorporate both.

This is literally the first step in the planning process, if you can call it that at this point. I'm interested in the experiences/advice of those of you who have made the trip.
