Being an airline pilot i travel a lot around the world, specially around EU. My "travel" kit is a D90 paired with 16-85, 35 1.8 for low light scenarios and sometimes with a 70-300VR. The 16-85 gets the job 90% of the time. Only time to time i feel the need to use the 70-300VR. I guess you will be fine with the 18-105 + 70-300VR.
