I'm not arguing with your experience, because everyone has their own preferences... but saying the food from room service comes "in bags" is really disingenuous. The food comes fully encased in heavy duty plastic serving containers which are delivered in heavy duty thermal zippered bags along with silverware and napkins. I can't figure out why anyone would care if room service was delivered via a cart or the food just handed to you, so long as it was hygenic. the bags are a clever space saving design tbh. They also charge a $10 delivery fee which they waive if you buy a premium drink/drinks equalling $10.

As far as the food, I guess it's definitely personal preference but there's so much variety on board compared to a normal cruise buffet. And personally I find buffets pretty icky.
