If they can get a developer to finance the project, there is no reason to extend. Knock-down or fully renovate, they’ll have new contracts to sell at an extremely popular location. Plus the reworking points chart, making those who own other locations pay more to stay there. Basically devaluing the overall point pool. Too much gain to not monetize.
Exactly --- And take into account changes in the park over 50 years, to maximize profits. Back when BCV was built, attendance at Disney was lower. Epcot wasn't a festival destination. True deluxe
DVC didn't exist, DVC was still somewhat lesser than deluxe accommodations -- OKW and SSR with their non-theme park locations. BCV was put in a corner of the Beach Club property rooms smaller than the regular resort, without views of the lake.
Since then, the newest DVC is more equal to true WDW deluxe properties -- GFV and RIV being the prime examples. And with the popularity of the Epcot area hotels with DVC guests for festivals, they could really sell a whole lot more rooms at prime real estate of BCV. So it would be very profitable for Disney to knock down BCV and put up a tower twice as large, bigger rooms and more rooms, to attract top dollar.
I think OKW was a little different due to the configuration of that property.
How often do you get to sell the same property twice?
I'm not sure the buildings have been constructed with a mind to climate impacts in Florida, which can be kinda significant.
But it's not just if the building is safe and sturdy. It's about whether the building continues to meet the desires of guests in a way that maximizes Disney profit. For example, by current standards, the rooms at BCV are small compared to the nicest most modern resorts. And Disney may feel that if that they can sell twice as many rooms at double the price if they made the resort nicer (and doubled the number of rooms).
Think about houses built in the 1970s, and how they feel today (50 years later). If they have not had major renovations, they feel tired and dated. Closets and kitchens feel small. The electrical isnt built for today's technology.
Now, many homes from the 1970s are still around -- And many are stunning beautiful modern homes -- But such homes have had massive renovations. They had additions built, walls torn down to expand kitchens, etc.
Not just "soft good refurbishment" but major major work. On a hotel-wide level, the type of work that can't be accomplished without shutting down most (or all) of the hotel for many many months.
