Pretty much everyone. The name changed in 2001 when DCA opened.
Disneyland refers to the original theme park and Disneyland Resort refers to the two parks, DTD, and three hotels. The website, tickets, merchandise, everything says Disneyland Resort on it. Note, in California, we call refer to the hotels as a "hotel" not a resort. In Florida, the hotels are called resorts.
Keeping this DWTS related. They picked some of the busiest days to film at the resort last week. Regardless, the cast and crew were beyond gracious, interacted with guests while filming and posed for pictures with guests after filming.
