I would recommend ItalyTours. June 2024 booked 3 tours. Best of Florence/Pisa, Best of French Riviera and Pompeii, Sorrento and the Amalfi Coast. All 3 were timely and informative. Drivers and guides were polite and enthusiastic about sharing their knowledge. They had water available, stops were explained and appropriate. Pompeii was hot. Take a small fan if you have one.
