Each Wednesday morning (as long as the Pope is in town) he has mass in St. Peter's - if you can secure tickets for an "audience" you are all set. They are free but you have to ask for them.
We showed up early, I bought a beautiful rosary for my Gramma and we waited along with all the other folks to see him.
thank goodness for digital cameras, at least I could take a picture with the digital display in the back - otherwise it would have been of the ceiling!
