Colosseum and Roman forum tour - Andrea was a wonderful tour guide. She is very knowledgeable and kind. We had a truly great experience!

Definitely Recommend! - I do recommend the quick tour it was very informational our guide was amazing! however expect large crowds it’s going to be hard to move around the colosseum and get pictures. We had a fast pass and we still waited for about an hour before we even got in.

Rome experience - Had a fantastic time and the tour rep igor was fantastic he shown us all around the ruins and explained everything very well

Just ok - We showed up for our scheduled tour and was told it was delayed an hour without any notification. The guide was challenging to hear, group was more than was suppose to be on tour. We’ve spent a lot of Viator tours so it was a bummer

HORRIBLE tour company - We scheduled a tour for 3PM. Arrived at 2:40. The CIS tour coordinator told us our tour was changed (no reason) and we should come back at 3:30. Came back at 3:30 and they said we would not be going till 4PM. Finally got with a guide. Walked 10 minutes just to get our tickets, then had to walk back. Finally met the real tour guide (He was great). The tour company gave our guide 33 people (but the coliseum ONLY allows 25 people per guide!!!). So then we weren't allowed in and had to wait for a second guide to arrive. Once we finally got in the tour was rushed so we could go see the Palatine Hill before it closed (4:45PM). For almost 100 euros each, it was horrible. Taking a tour is great. The guide was great. But the company (CIS) is horrible and I would not reccomend.

Bad experience - They changed my tour schedule the day before. They gave us an app to DOWNLOAD and listen solo. IT'S NOT WITH GUIDANCE IN PERSON. THE APP'S A WRECK. I DON'T RECOMMEND IT AT ALL !!!!!!!!!!!

SCAM wasted our time and money lost our tickets! - This was our first day in Rome. When we met our guide, they were late, did not have a guide shirt on or flag, and get this, LOST OUR TICKETS AND THEN SAID THEYLL GIVE US 50%. THIS IS INSANE, I EXPECT A FULL REFUND PLJS COMPENSATION FOR MY TIME, AND TAXI. VERY UNPROFESSIONAL PLEASE REMOVE FROM YOUR SITE. I planned this trip from my mother and sisters, these guides and company gave us such a bad experience. We spent so much time and money to get to Rome to be told they lost our tickets and don't even want to refund us? Get off site, and report. I expect my refund today.

Bad experience - Worst experience ever. Booked the tickets for Colosseum and 2 hours before I got an email saying that the tour was cancelled.

A SCAM - This company is a scam. We showed up on time at the meeting place for our tour. We were jerked around by the company for 30 minutes before they told us our tour was cancelled and they had cancelled our tickets. Forcing us to wait in the extremely long ticket office line to even hopefully get into the colosseum. Avoid CIS at all costs

TOTAL SCAM AVOID AT ALL COSTS!! DO NOT BOOK WITH THIS GROUP!! - We showed up early to the meeting point only to have the tour operator guy tell me my tour was canceled. He provided no explanation and seemed completely unapologetic. He never notified me about the cancellation prior to showing up. He then told me that we could do a tour at a later time that afternoon. We again showed up early at the meeting point and the man was no where to be found. He then appeared 5 minutes after the tour time and told us “sorry but you were late, you can go on a tour in an hour”. Before we left, he told us that we could go on a tour with a different group. He claimed that he sent me a confirmation of a refund. I checked my email saw no message and argued with him for a good bit before a refund notification was emailed. The refund still hasn’t cleared and I’m not sure it’s legitimate. He pointed us to another tour from the same company who was a lady wearing a hijab and she told us that we had to pay €40 per person to join their tour. We agreed as it seemed like a fair price and the refund was seemingly in process. We were then walked over to the forum and dropped off in the “purchase ticket line”. Our tour guide was an African woman who told us to wait in the line. She never introduced herself to us or others in the group. She then pulled out her phone and began screaming on the phone profusely for 20-30 minutes. After waiting in the line in the hot sun for a bit longer (around an hour or so total) we decided to just get up and leave. So much for “Skip the Line Tickets”. It was very disappointing but we realized this group wasn’t even legitimate, they were con artists who were completely unprofessional. These people are TOTAL FRAUDS. I’ve gone on a lot of tours in my life but this was head and shoulders the absolute worst experience I’ve ever had with a tourism group. TOTAL SCAM AVOID AT ALL COSTS. I advise anyone that under absolutely no circumstances is it worth it to deal with these people. Go to the Colosseum on your own or hire a local ITALIAN guide. I cannot emphasize it enough, AVOID CIS TOURS.
