We went here to see Celine Dion concert!!! She was wonderful and the performance was amazing! As for the Colosseum. Is pretty clean. The seat was ok. It was like any other theatre seat. We got our seat around the 20th row in the middle. It was a pretty good view. I wouldn't recommend anything past 40th row or even the top. It would be hard to see the singer's face and expression back there. I would definitely go back if they have another show that interest me.
