tuscany for 3 days


New member
hello, my husband and i plan to be in tuscany with our 6 year old daughter in july for 3 nights. we will arrive from naples and then go ahead to venice or lake garda. we plan to hire a car to move anout in tuscany. would like some help with:
where to stay centrally so we can visit pisa, san gimignano, florence etc.
where to arrive from naples so as to hire a car.
how to get to venice or lake gards from here-continue driving or return the car and take a train?
should we even consider a day trip to cinque terre in these 3 days, or will tuscany have enough to offer? (we are speding a few days on the amalfi coast befor coming to tuscany)

any ideas and suggestions are welcome.
thank you
