You've always been terrific sources of wisdom and suggestions. I'm going to be back in Munich this summer for the opera festival in late July. For the past few years, I've tagged another city on to that trip -- Vienna, Budapest, Prague, Berlin.
This year, I was thinking of going to Lisbon first, and then to Munich. However, wondering if late July will be uncomfortably hot in Portugal. Should I save that trip for late spring or early fall? Munich itself can be pretty humid (with occasional rain showers) in July.
I have about 6-7 days to play with before arriving in Munich. It's such an open itinerary that it's almost overwhelming in options but weather would be a factor.
