Since we get in around noon on the 1st day, we're looking at just the 2 hour orientation. Day 2 we'll want to do Ancient Rome in the morning and wander the rest of the day. Day 3 will be the 4 hour Vatican tour followed by possibly the Italian Wine Walk (nice way to end our brief visit!). Day 4 we fly home early.

We'd like to do the underground Rome, but it's not offered on the days we are there. I'll either inquire about a private tour or find another avenue to see that.

Thanks again for the advice.
