For me, the Final Jeopardy category and answer are Walt Disney World Resorts and This is the expected lifespan of a Walt Disney World Resort hotel, respectively.
Now, because of DVC conversions, we know that three Polynesian longhouses, one Grand Floridian lodge, and the entirety of Animal Kingdom Lodge (Jambo House) and Wilderness Lodge (Copper Creek) will be around for 40+ years. However, I doubt that any of these hotels were built with the expectation of achieving historical landmark status and some are certainly approaching the end of their lifecycles. Respectfully, the lobby may have been refreshed and reimagined but the island buildings of Caribbean Beach are over 30 years old and, in some places, the concrete and stucco show it. Personally, I think it was easy for decision-makers to raze Barbados and Martinique because the visible aging is known and, in time, the cost to maintain these buildings will exceed replacement.
Do we think that the juxtaposition of these additions with originals is because the originals may be razed in the future?
With the new DVC tower at the Disneyland Hotel, for example, could the stark difference be an indicator of the potential for three new towers at the resort? It does not seem to be designed to fit along with the existing towers as the Tomorrow Tower.
