I think the 18-200 is a really nice lens. Gives you a ton of flexibility. If I had the budget and to do it over again, my travel kit would be a 10-24 and a 28-300 (longer with not much more size, and seems to be rated better for sharpness, etc) to go with the 35 1.8 I have.
Here are a couple shots I took with my 18-200:
First day I had it: Facing the Hill by e24mpwr, on Flickr
105mm @ f/10 (blew the focus a little, but still looks good)
