I am going to the Essential Europe trip on May 18. Is there a way that I may attend a papal mass or any mass in vatican city? Has anyone done this before?
It all depends on when you are going to be in Rome (what day of the week) and what else you want to see in Rome. I didn’t go to Mass when I was on tour but am going back to Rome in a couple of weeks and have organised tickets for a general audience mass with the Pope- these happen on Wednesdays. This is the best website http://www.vatican.va/various/prefettura/en/udienze_en.html, if you are there on a Wednesday use the link on this site to organise tickets (they are free) and they earlier you apply the better chance you have. This website also lists the times/dates of other upcoming masses and events.
Hope this helps, have a great trip
