Good question. I did that cmparison after the trip (I was gone for a week to New Orleans and D.C.) as I was comparing the 18-250 to the older 28-300, which I liked very much as well. I was more interested in seeing whether I'd use the wider part from 18mm to 28mm, and I did. I don't know the percentage of shots I took at the long end, but I occasionally did. I can see in D.C. it wouldn't be as necessary, however I'll often use the close focusing capability (focuses at 18" at all focal lengths) as a sort of "macro" for nearby objects. Even with the slow aperture of f/6.3, at that focal length you can still get a very shallow DOF for isolating a subject. Also, this lens is pretty small and compact, about the same size as shorter lenses, so I figure it's not costing me anything in terms of size/weight to have the extra length if I need it.
I'm sure there are other lenses that would serve as well or probably better. I just found the 18-250 works well for me as a travel lens. If there's any place where you could safely leave the telephoto at home, D.C. is probably it considering how compact it is, and all the museums you'll be in.
