FlorenceTown, a local Florentine tour and destination management company, just announced they have secured Vasari Corridor access through October, 2010. This is basically one of the only ways to see the Vasari Corridor, unless you have a personal friend at the Uffizi :)
You can book this on-line from our partners at Viator: Vasari Corridor Walking Tour. Tour starts at 3:30 PM, Tuesdays and Fridays only!
