Visit The Vatican Museum:
If you are heading to the Vatican City this year, you might consider hopping on a guided tour. Of course, visitors are not required to be part of a tour but the Vatican Museums' outstanding art collection and the sheer size (stretching over 9 miles) of the Vatican Museums really does require a bit of guidance.
There is a plethora of options for touring but keep in mind that the quality of tours can vary immensely. The tour company you choose can make or break your trip so be sure to do your research in order to find the tour company that best fits your requirements.
