I have booked a tour with Context at Steve's recommendation. But it is for the same day we arrive in Rome. Context for afternoon tours does not pre purchase tickets so we have to get them ourselves. we will only have 1 hour at the most to get the tickets befor the tour I know we are cuting it close is there anyway to pre purchase the museum tickets?
Went on a Vatican tour on July 20. Our tour started at 12 noon on a Friday. Everyone has to stand in line now whether or not you are on a tour. We got in line at about 12:30 and were in line for about a half hour--wasn't bad in the afternoon. In the mornings I understand the line is much longer. So, it depends on what day and time your tour is. Not sure about pre-purchasing tickets. If your tour is in the afternoon I think you'll be o.k. with 1 hour.
