I'm trying to see as many churches as I can while staying 3 nights within walking distance of the Colloseum. The first day in Rome I thought it would make sense to see Saint Paul's and San Clemente first since they are both on the same metro line and Saint Paul's opens at 7 am, before touring the Colosseum, etc. I'd also like to see Saint John's and St. Peter in Chains but I'm not sure when to work them into our itinerary. How long should we allot for each church? Are they all worth trying to see? How many hours should we allot to tour the Colosseum area? I read if you buy tickets at the Palatine Hill you avoid waiting in line at the Coloseum. Is the Palatine worth seeing? Are the 4 euro guided tours of the Forum worth doing if we have a guidebook? About how long do they last?
On our second day, a Sunday, we'd have time to see things from about 2 pm on. I was thinking of seeing the Pantheon and some neighboring churches. Any specific suggestions on how to spend our time then or on rearranging our schedule on the first day? We will be touring the Vatican/St. Peter's a week later on our last day in Rome. Thanks for your help!
