That is great that you enjoy the rooms, a lot of people do and some do not. In our opinion, they are dated. We did not stay DVC, we don't do timeshares. This was a Courtyard-Woods view room category that faced GRR near Soarin'. Dated meaning dark, wood paneling that is always going to show age faster, small bathrooms, less counter space, less insulation from the hallway. We had a room with a tub rather than a glass shower, which didn't help it feel updated. We paid rack rate booked through the Disneyland website (I want to say $800? per night for the room), so it's not like we were put in a less desirable room because we booked third party.
The GCH has the location, grounds, pool, cabanas, restaurants, CMs, and lobby going for it that make it unique and special. The rooms, however, are not one of the reasons that the hotel stands out from the rest which is fine, but it is what it is. I hate being negative, so I will say that the room was clean and the beds were comfortable. The Chip and Dale painting was cute, but doesn't hold up when compared against Disneyland Hotel's lighted/musical headboard.
I didn't take pictures of issues in our room because it didn't bother us enough (and again, I hate being extra negative), but it had similar on the wood when staying there (taken from trip advisor). Not completely obvious or impacting functionality, but I would consider this to be dated:
