Gx85 for Travel?

As a current GX85 user and (in M43 practice) solely a Panasonic (GF1, GX1 and GX7 before the GX85), I've gradually pared down my travel lens collection. Given the insight provided by my wife about "photographic" versus "holiday" travel; plus my advancing age; plus my Nikon Ds80, 200 and 700 experience and the weight requirements of multiple lenses with the Nikons, I've eventually trimmed my travel equipment down to the GX85 (my GAS does not preclude a potential future GX9, for example) and one lens mounted while out and about, and a second, often never used backup lens in the bag (but I've increasingly less inclined to carry a bag while shooting on a trip and leave the backup lens in the hotel safe).

I'm now settled on the 12-35 f/2.8 Lumix, taking advantage of the Dual-IS connection with the GX85, with the 15mm PanaLeica as the backup back in the hotel. As I've posted recently I've even spent two weeks in Paris and Dublin with just the 15mm and never much thirsted for another focal length.

I have to add that my wife and my travel trips in our later years have been, luckily, principally to very urban locations in European cities and towns and long lenses have not been particularly useful. My practice on trips over the last ten years had been to take three, then two lenses on a trip, plan each day's touring and select just the lens most suitable for the day's touring, e.g., museums, churches, historic sites, etc.

I know that minimizing the potential benefits of a camera bag chock full of lenses has limited my options and might work well for only a very few others, but there's room in travel and photography for many different approaches
