We will be arriving on a Sunday at 7:45 AM. The TI at the airport won't be open, and I have seen different hours from various sources. Some say it opens at 8 AM, others say 9 AM. If it is 8 AM, then we can get our Roma passes before leaving the airport.
Otherwise, we will be taking the shuttle into Rome and after reaching our hotel, we will take a short walk to Spagna station. Any opportunities to get a Roma Pass before getting on the metro in this example? Thanks.
