While the tour itself was pretty decent time wise, we were delayed an hour in the tunnel for construction. We found out later this is common. Tour guide did not realize we had a return train ticket booked and paid for by the main tour company. We were late to our train form Naples back to Rome and had to purchase new train tickets as they were not exchangeable. Lack of communication but we did get home. The tour felt very rushed in actual Positano. Had 45 minutes to walk around on own. Second time there on a day excursion. Tour guide was knowledgable.
