I'm trying to think of all the cities U2 could do multiple nights in that they aren't this year.
Philly, Washington, D.C., Atlanta, Miami, Dallas, Houston, Detroit, Toronto, NYC (in a non MSG venue), Las Vegas, San Diego, Los Angeles?, Seattle, Edmonton or Calgary, Minneapolis.
By not doing single nights, they'd be leaving out Portland, Salt Lake City, Kansas City, Omaha, St. Louis, Milwaukee, Oklahoma, Nashville, Tampa, Raleigh/Charlotte, Charlottesville, Pittsburgh, Buffalo, Albany, Hartford, Cleveland, Indianapolis, Winnipeg, Ottawa, among others. Obviously they won't do all of those cities, but they could sell out 1 arena show in those cities. Most bands DO play those places when they tour, and U2 used to as well.
