DO you have to make advance reservations to se Vatican Museums and Sistine Chapel?

This week I am going to Rome. Of course, one thing I will be concentrated on are Vatican Museums and Sistine Chapel. However, I do not know whether it is necessary to reserve that in advance, or can I just go there and buy the tickets? Thanks in advance, it means a lot!

As you are obviously aware, among all the attractions in Rome, Vatican museums and Sistine Chapel are probably the most popular, at any time of the year. That being so, it is obvious they are always crowded. If you check various tourist agencies, you will see they have an organized visit to these places, but do not provide you with a ticket. On most cases, you will have to stand in line and get a ticket practically on your own. Now you might want to consider organized visit to the museums and Sistine Chapel, especially if you have never been there before, as it is much easier see all there is to see without wasting too much time. Enjoy the stay!
