Many places are the same ones as with the Stones. Arenas in USA, also some in UK, mostly stadiums in Europe. For crowd capacity see:

Most arenas are 15,000 +/- 3,000. Most stadiums are 50,000 +/- 15,000. U2 ticket prices are only 50% of Stones ticket prices, so it is not a real comparison. Like oranges vs. potatoes.
