Joanne ,
I am planning to go on a cruise on May 03-08 that stops in Florence. I will see what I can find there although is a one day stop only. In 2004 I went to Venece and there is a company that manufactures bottle water that resides in Milan, Italy. I you are interested I brought with me the bottle and I will give you the address, now I am at the office.
Be well,
Sylvia
