We are currently booked with Walks of Italy night tour of the colosseum + underground for June. The tour is supposed to be a little over two hours, but I read an isolated review that stated they ended up being in the colosseum for only 45 minutes of that time. I know not to believe everything you read on the internet because...it's the internet, but has anyone taken this particular tour, and if so, what was your experience? How much time did you spend in the Colosseum?
As an alternative to this fairly expensive tour, we are attempting to secure tickets for the underground tour through the official website, but they only open windows for booking a month in advance so far and they sell out FAST. Currently, May is not yet available for booking. Sigh. So, I'm pretty sure we will be spending the $$ on the WOI tour.
