I don't think that they are really of the same hotel... I think last week's Hollywood Hotel Pin may be a different hotel, my current guess is Hong Kong Disneyland's Disneyland Hotel. If you go to the Hong Kong Disnyland site they have only 2 resort hotels, the Disneyland and the Hollywood. The HKDL Hollywood Hotel is all blue and peach colored (like this week's pin) and the Hollywood Hotel pin from last week really doesn't have any blue on it at all. It resemble's Hong Kong's Disneyland Hotel more. They never even put last week's on the newsletter page so it could be a different hotel entirely, but I don't think that they are both of HKDL's Hollywood Hotel.
Well researched! Most likely they are two seperate hotels but VMK didn't think about the confusion of putting two "Hollywood Hotel" pins out in the same week!
At HKDL the Disneyland Hotel is identical in architecture to the Grand Floridian, the Hollywood Hotel is a bit like the Paradise Pier hotel, but with two wings on the side. This weeks pin is defiantly more like the Hollywood Hotel, as Raineforst said.
