The vatican tour was three hours with a group of ten and was €75 per person but worth every penny! Not only did you skip the queues to get in but the guide brought the whole experience to life for us, it's so packed in there you would never get close enough to understand unless you had seriously studied it before you went, the tour guide Sara (pronounced Sarah) was superb and we were massively impressed. Her detail of the entire tour was so interesting and her service and attentiveness to every guest superb.
The Colosseum tour was with Alessandro and lasted about 2.5 hours and this was just a group of six of us. Alessandro was an archaeologist by training and had actually worked on the Forum dig for several years and his knowledge was amazing, we felt transported back through history, and because he knew it all so well he also knew where to take us for some of the best photographs of the trip! Something we noticed other groups, didn't experience. Alessandro was an amazing tour guide and we would definitely recommend visiting the Colosseum with him!More
