Varenna or Vienna or something (pictured) is a sleepy fishing village.
Menaggio, or it might have been Menagerie, has a nice centre that's too small.
Villa Carlotta is a garden with a villa in it. The gardens are very agreeable but not in searing, skin-scorching heat.
Tremezzo is like a strip mall from the poor side of town.
We spent an hour waiting for the boat back to Belaggio. The timetable is correct but the error bars on the boat arrival times are long indeed.
I'm sure Carlotta is some kind of codename for a spy.
