Thanks, I'll check out you Florence for Free link.
Also sorry, guess I was unclear. I've been to Florence as a tourist perhaps ten times, and visited almost everything included in the Firenze Pass, some several times (e.g. Santa Croce). Was hoping that you might have suggestions for some of the other churches that are not visited as often by those on the three day Florence tour. Keep hoping that one of my visits will allow me to view ALL of the cenacola, which will take a bit of luck or a few weeks, with an eye to their irregular opening times.
