Generally we looked for repeated patterns of comments when searching for all-inclusive resorts when we did Mexico last year and then cruises which helped understand personal preference over company-style. There have been a lot of threads for example detailing some very lackuster overall shared opinions regarding cruises for
DCL on the food front and while some of that is going to be personal preference other shared experiences seemed to be more of an issue on DCL's side and sometimes that was just a specific cruise where it happened. It's gotta be hard to please a ton of people from all over though.
