I'm on the Gem next month and you had me worried but I feel better after reading some of the replies.
I don't care about cookies, towel animals, or lox. I keep my cabin clean and prefer just having once-a-day service. I'm not a fan of long lines at bars but my alcohol tolerance is so low now that I'm fairly certain one cocktail will keep me content for a couple of hours.
If I think a restroom is disgusting I find the nearest worker and let them know.
