Thanks everyone, some interesting responses regarding your travelling kit.
Yes, I agree about your Chicago shot Jacob, a great shot.
Dave, I fully understand your viewpoint, and if wildlife were a main interest when travelling, I can see why you need to have a long lens with you.
However, as my interests when travelling are mainly landscapes and people, I'm more than happy to just take my G1X, small tripod, remote release and a small Canon flash.
A further illustration of the compact quality I get, and to complement the Budapest Parliament at night shot, here it is by day -
