I agree. I routinely take a book with me everywhere. The book visibly lets others, including servers, know I’ll be returning.

That's us as well. DW likes to dress up for Chic nights and expects me to do the same. I get the same comments as well.

Looked into this just before the pandemic as we were thinking of disembarking in Naples because we wanted to spend a few days in Sorrento and it would save us a day of extra travel. Bottom line - you need to let Celebrity know in advance that you want to do this due to local customs and immigration laws. Celebrity will let you know whether you can legally disembark at another port or not. It didn't appear to be a problem for Italy, but I don't know about Greece. This also lets the ship know that you will not be returning so they don't spend time and resources trying to locate you. You will be responsible for taking off your luggage.
