For Cinque Terre crowds, I see the advice to avoid weekends and to avoid days cruise ships are in port at La Spezia. I will be going in mid-May and can choose a Saturday & Sunday (May 9 & 10) with no ships in port, or a Wednesday & Thursday (May 13 &14 ) with Allure of the Seas (6,000 pax) in port one of the days.
So I'm confused which option would more impactful for avoiding crowds?
