Yes, I also highly recommend the night tour of Colosseum.

I've done day tours several times. Last time was was in October last year, and it was insanely crowded so I can't imagine how it is now. Definitely feel like there are more and more tourists in Rome.

There were a lot fewer people during the night tour, and we got to see more (getting below the floor of the arena), but it was also quite a lot more expensive as I remember.
