We've been told that mask wearing on cruise ships is an EU requirement, so it's not NCLH going on its own. Things are different in Europe. France required an on line application PCR code with vax info in order to get into shops & restaurants, but most never came through for us. Some restaurants would accept our vax card. Portugal required antigen tests for all guests & crew before arrival and Splendor had 100% negative. Also in Portugal we can only go ashore on a Regent excursion and tuk tuk and hop on hop off tours you must stay in the vehicle. No independent walking, drinking or dining. Spain is more relaxed, but most people on the streets wear masks.
