Not everyone has been to Hollywood, and for some they would enjoy seeing the landmarks and tourist traps.
Not everyone is a Disney fanatic that dissects every issues Disney has and is aware of the mistakes, issues and other problems Disney have. Many just enjoy the movies and parks for what they are. Even with the issues raised here all the time, Disney still provides an unbelievable product. Could it be better? Sure, but for most, it is better than they expected.
As for the Disneyland Resort, this terms refers to all properties in Anaheim, from DL to DCA, to the hotels and Downtown Disney. It is not just the DL Hotel.
Best part is, if this is something you would not purchase, you do not have to, but for many who do not live in close proximity to the park, this may be the once in a lifetime vacation.
