I have found two holidays in these places and trying to decide which to go for. Can you sell either one of the areas to me as a good choice? We are a family group of 7 people (5 adults and 2 children aged 1 and 4)
We went to Tuscany last July and stayed in a villa. It was lovely but extremely hot - not sure if Croatia would be hotter or colder.
Tuscany is a wonderful place but we got to see very little of it as we were 3 families and all the places of interest like San Gimiano and Pisa are more geared to walking around drinking in the atmosphere or enjoying some wine rather than the interests of young children. however you are a mixed group so it might work if you find a nice villa.
