I do not understand your obsession with the number of people that do not drink or go to bed by 9Pm (do you do bed checks)

Who really cares
some may have medical issues or just do not drink
some people smoke many do not
If Oceania is so bad why do you keep booking cruises with them surely there must be other cruise lines that would suit your lifestyle
Rhetorical question no need to reply
