The Medici Tour is definitely the best tour for senior travelers. It is designed to provide seating whenever the guide speaks for more than two minutes, reducing strain on the knees. The route avoids tourist crowds, ensuring you can hear the guide clearly. The tour also takes you inside every landmark along the way, offering a deep understanding rather than just a brief summary. Additionally, it provides shelter from the rain, has a perfect length, and finishes at lunchtime in front of several authentic Florentine restaurants.
