I only know of one hotel in all of Tuscany that offers a proper supervised kids’ club with a dedicated facility, instructors, and full activity schedule: Hotel Adler Thermae in Bagno Vignoni. The reason this amenity is rare is that parents don’t really seek out kids’ club facilities while traveling in Tuscany with kids as there is so much to see and do together. Adler Thermae, however, is the exception, as it offers a wonderful thermal spa and wellness center, i.e. parents have good reason to make use of childcare.
