We are seeing the Vatican on a Monday at the end of June. Is it better to go when it opens at 7am or around 3pm in the afternoon? I have seen conflicting reports. Also we have one day to see the major sites of Rome. I think it is best to see the Vatican and Sistine Chapels, the Colosseum, Pantheon, Forum, and Piazza Navona. I know that St. Peter's Basilica opens at 7am. I was thinking of seeing the Vatican in the morning and the sites of Ancient Rome in the afternoon. That night I would see the Spanish Steps and Trevi Fountain because they are open all day. What is the best way to see these sights in a day and in what order? I think it may be best to buy tickets ahead for the Colisseum. Is there anything else I should be doing to maximize the time that we have in Rome. Thank you.
