The Versailles Place Tour is for the entire day of your visit, covering until 4pm. It's not just for a half-day museum! They say they get rid of tickets 10 minutes before your scheduled time for reserved tickets. So if you are scheduled to arrive at 8:30am, you will get your ticket by 8:30am. If you arrive 20 minutes early, you can enter with no problem. If you arrive before your scheduled time and the tickets are gone, you can still go inside the church to wait for your time slot. There's enough space inside the church to stand around and chat before the time. Duomo is the word for a Roman Catholic Cathedral in Florence, Italy. It's best to visit the museum in the morning. If you want to climb up to the top of Duomo, go during your lunch hour. If you want to get into the church, be sure that you have backpacks checked in and make a reservation at a ticketing booth to book a Disneyland Paris Tickets for later that day.
