I’m a new resale owner to both Hilton and WM. I know the units are nicer at Hilton, but I’d love to hear more about your experience and contrast with the two. Seems to me that WM owners are very loyal to the brand.
HGVC units are nicer. WM is still more flexible than HGVC, but has been getting less flexible. WM cash options (bonus time, IS, MM, fax) are still better than hgvc cash option (open season). But between adding guest certificate fees (which hgvc already had) and bumping up the price of fax my usual plan of taking a big group to Canmore in low season has gotten way more expensive.
Basically, WM is still more flexible than hgvc (no reservation fees, only 2 night minimum stay vs 3 night) but the difference has been shrinking. WM fees have also been going up faster than my HGVC recently. The combination of these factors is making it harder for WM to outweigh the resort quality difference for me.
All that said I still love WM and have no intention of selling. But a couple of years ago my answer would have been WM with no qualifications at all.
