We attended the early morning tour which was excellent. Checked in at the Ultimate Italy office at 8:30, and then had time to admire the Colosseum exterior from a nearby cafe before the tour commenced at 9:15. Our guide Katya was fantastic - very knowledgeable and funny too. She moved us along at a perfect pace, brisk enough to keep to the schedule but still allowing enough time to stop and listen to the information, take photos, etc. The underground area was fascinating and a welcome break from the crowds (and heat!) in the higher levels. The tour finished in the Forum, leaving us to explore the area and the Palatine at our own pace which was ideal. If your guide doesn’t offer, make sure to ask for your paper ticket at the end which allows you entry into the various museums on the site! You can enter any of the areas open to “full experience” ticket holders which was a nice surprise. Overall would highly recommend, and thank you Katya for a wonderful experience!
