We got this because we were told the wait at the Vatican would be much too long without it.
We arrived at what we thought was the designated spot on time, and there was nothing marked, and no one was here to meet us.
We asked, and some Vatican City guide who has no affiliation with this business took us down a long set of steps to the road below, where he dropped us off inside a building that he thought was correct. Then the people in that building told us no, we were in the wrong place, but they graciously took us two doors down to what was the right place.
We ended up waiting for about 45 minutes in to finally get our "expedited" entry, so I'm not sure how much time we actually saved.
At least everybody was very nice.
