Location Suggestion in Switzerland and Italy

Hi Friends,

I’ll be in Europe for a two-week travel in September.    During the stay, my son and his fiancée are planning to spend two days for wedding photos.

Wonder any of you have any good locations in Switzerland and Italy (not necessarily big cities) to recommend for such occasion.

I’d appreciate it very much.

I’ll arrive in Munich first and the rest of the journey hasn’t been finalized yet. Perhaps we will be meeting somewhere, sometime then.

Tom

Received many good suggestions in just a few hours. Thank you!
