We arrived from the US, got settled in our room and realized our hotel was two blocks from the Colosseo. It was such a shock walking down the street with modern stores in probably 100 year old buildings, then looking down the road and seeing a building created before 100 AD! We walked around the perimeter and up into the hills. The next day, we found our tour company had purchases tours inside for everyone. There are queues everywhere and crowds galore, so bring your patience. There are elevators, but most of the travel to get inside requires steep steps. There is nowhere to sit, but is to be expected in a 2000 year old building. It was stunning to stand in a space where people stood almost 2000 years ago, watching prisoners fight animals for their lives and gladiators fight to the death. Also, found out later this is one of the Seven Wonders of the World!
