We have a couple threads about where to go during the summer:

• Best Eastern Europe Summer Beach Destinations
• Summer 2011
• Places to go and places to avoid In Europe during the summer

For those guys who don't care much about beaches or resorts, what are some big cities to stay in for at least one month where there isn't a big decrease in locals leaving town? From the forum these two have popped up a couple times:

Montreal
Stockholm

South American cities are also a fine choice since they're experiencing winter. Any others?
