We visited the Vatican on Monday, June 15,2009. At 9:30am, there was no line into St. Peters and at 1pm, there was no line into the museum. We were fortunate to participate in the Scavi tour and it was one of the highlights of our trip. Our tour exited at St. Peter's but we did not have to wait to enter. We were allowed straight in. We did use the official Vatican tour guide for the museum and were very pleased with our tour. Even if I knew that I would not wait in a line for the museum, I would again book the Vatican tour. There is no way to appreciate it fully without a guide. After our tour, we exited back at St. Peter's. Again, there was no line.
