When it come to incidental benefits, they are always going to put that language in place because things happen and it covers them legally.
The AP is offered by Parks division and if they stopped selling them,
DVC can’t sell them to a member for points.
They have to make it clear that things could change.
I do not expect DVC to do that. Program aside, they can stop selling OTU points at any time. I do think it being a paid program actually makes it less likely they stop unless it’s out of their control.
