My wife and I are going to Rome for our 45th anniversary. We're staying at the Marriott Grand Flora for seven days. Do they have someone on site that can assist with with reservations for historic sites and day trips or should I order ahead of time through Viator? Also, does the hotel have an ATM on site or nearby? The hotel website doesn't have this information. Also, as a silver elite I'm not sure an upgrade is possible either. I am grateful for any help.
