I'd suggest the 16-80 and throw your 12mm in the bag too, to carry when you'll be in town sightseeing. Leave the long lenses at home.

Maybe also get a XC35mm f2 for low light. It's cheap, light & small.

 

Hello, new to the forum, but spotted this post. I live in the UK and have visited plenty of Europe. It depends on your interests, but lots of the classic cities, history and architecture can be small and tight. So personally I’d take my 10-24 too if that was possible for certain subjects. The older and old town cities with the history are very tight and small and you can’t always walk back. BUT, this depends what you intend to shoot!
