After spending nearly a week in WDW and then nearly a week on DCL it’s a bit shocking how different the level of CM service is, the CMs at WDW were all good and we didn’t have a single issue with any of them but the CMs on DCL are the most friendly and amazing people anywhere. It’s a noticeable difference.
Definitely an apples and oranges comparison as the guest to CM ratio is probably 100 to 1 at WDW vs probably 2 to 1 on DCL but everyone from our room attendant, to our servers, to our bartenders, to the CMs manning the aquaduck entrance and the spa entrance were just incredible on DCL.
DCL also seems to have retained the old appearance standards, we didn’t see any unique hair colors, no visible tattoos, no “personalization” like you see with the CMs at the parks. Most the CMs on DCL seem to be from foreign nations though so maybe that’s more a symbol of American culture rather than a Disney standard.
