We are going to Rome..

and it is going to cost less to go for a weekend in Rome on the way to Ethiopia than it cost for Ariel and I to get our six immunizations today (each). We were hoping to find tickets that allowed us to have a short layover, and today our travel agent told us she had found some for just a bit more than the straight shot was. I am trying to hold back and not use as many exclamation points in my blog writings, but this time it was hard. Anyone have any suggestions for places they loved in Rome? I understand that Rome in August is going to be very hot, and crowded with tourists and is a terrible time to visit because all the Romans are on the coast enjoying their European vacation pay - but I can't be too picky.
