Skip the Line: Colosseum, Roman Forum, and Palatine Tickets

This was our only disappointing tour we had with Viator, who we used exclusively for our trip. We had scoped out our schedule and timing two days before, but we were not prepared for the Sunday closing of Subway B (one of only 2 lines in Rome, and the only one serving the colosseum). Consequently we need to walk from Termini (junction of Metro A and B) to the colosseum using a marginal map - The Italians like to skip the naming of streets all together, as well as change the name of a straight road every block or so, so as to honor the most words possible in the Italian dictionary. We left our hotel with plenty of time to be at our 11:45 tour, but through various unexpected detours and extensive map reading we were not able to reach our meeting point until 11:55. There was no skip-the-line representative there to give us any options - we asked all the other English tour givers and we were in the right spot, but they had just already left. With the metro being closed, they had to have only a handful of folks who were able to make that tour. We stood around the meeting spot for 90 minutes hoping someone would show, or maybe another tour leader for a later group, but to no avail. We only had one day left in Rome, and that was spent on another wonderful tour of Vatican City through Viator, so there was no chance to rebook. This was a big disappointment, but the only one we had with Viator where we thought there was significant responsibility by the tour operator.
