True, but that requires that Disney cash rates increase at a significantly slower rate than the increase in MF's, and there's a good gap between the two currently. If you look at a Grand Floridian cash rate, slow season, 25% discount, you're right at around $650 per night out the door (without parking). Right now, that VGF standard view villa is going for 16 points for that same stay. Based on MF's alone, that's the equivalent of 55 Vero Beach points per night based on 2023 MF's. If you used VGF points for that stay, MF's only, it comes out to 89 points.
In other words, the annual maintenance cost for the points required to book a room at VGF is $192 per night using VBR points, and $112 using VGF points. Versus the discounted cash rate of $650 per night.
