My family of 5 all adults will be in Florence for 8 days and my husband wants to make sure he gets to see some water. I have read up on Cinque Terre, and it looks amazing - we can do a day trip there from Florence, so it is doable. However, as I am doing my research, I am reading some say do not even go and that it is overrun my tourists. Any other suggestions for a day trip? We will be traveling at the end of September. Thank you in advance!
