Thanks so much to Hivaoa1 for letting me know that the Livorno antique market no longer exists. I loved reading your Livorno Page! We may just rent a car at the cruise ship port and drive to Arezzo. If not, are there any antique stores or areas in Livorno to shop for antiques on a Sunday? We sound like old people but we're only in our 30's but we love antique shopping. If anyone knows if there are antique shops in Livorno, please let me know.
Also to Hivaoa1, we live in Los Angeles near all the surfing beaches (Malibu, Santa Monica, Laguna) so if you ever want any information, please feel free to contact me (firstname.lastname@example.org). Thanks again for your help!
