For our last day, Jack and I bought a ticket one on of those hop on/hop off sightseeing buses. We were going on the red one, but the tout gave me the irrits so we went on the green one. Possibly it wasn't as good but all Jack cared about was seeing the Colosseum. In retrospect we could have just caught the metro there and saved ourselves some euros but Jack loves those buses and desperately wanted to sit upstairs. We saw some other sights of Rome but Jack certainly wasn't disappointed in his first glimpse of the Colosseum, even though part of it was clad in scaffolding. An American tourist sitting near us asked his mother if they were "adding on". Bless.
