Especially on DX, it is a really cool lens to have. For travel photography, I could easily see a kit that is the 11-16, 35 f/1.8 and the 18-200. I recently traveled to Europ and Asia for four out of five weeks, and these were the 3 main lenses I used.
I love my Tamron 28-75, and it is what I use 65%+ of the time when I'm shooting people and landscapes, but those three lenses cover a lot of span and shooting situations. My 11-16 was awfully cool to have when I was trying to get a lot of real estate in the frame or in dark churches...
