For me, it’s primarily the ability to book at RIV, DLT and any new resorts - which may include Poly.
I also like the idea of being able to use the points if ever needed for
Disney Cruise and Adventures by Disney. I *know* that’s a terrible use of points and presently we do rent points out and pay for them with rental income. But I like having options, especially if renting ever becomes a problem or the market dries up, to know that we have that option.
That said 2/3 of my points are resale, so our direct points won’t go far. But that’s why sometimes I am tempted to flip some contracts to buy direct, and may do that when PVB2 comes along.
