as stated above, only you can really know what to do since you know how you shoot best
I recently spent 10 days in Budapest and knew I would be walking a lot and I wanted to travel light. I took my X-T1 with the 27mm and 56mm. Didn't regret not having anything else. Travel was easy and I was never bogged down no which lens to use. I kept the 56 on most of the time and switched to 27 is I needed wider. A lot of people would not think this sufficient, but it worked really well for me. Point is, figure out what is really important to you and chose the appropriate lenses.
