My perspective is a little different than what has been expressed above, but we have MAX via a HGVC retail purchase and we have used it to stay at a DRI resort. I voted $1-2500 if I owned HGVC and wanted to add MAX. While I fully understand that HGVC resorts are far nicer, for us personally, we have been fortunate enough to actually live in nearly all of the locations HGVC covers and so those locations were not attractive to us. Not that they aren't stunning, but we have just extensively visited in those places and seeing new vacation locations is what matters to us. We aren't really lay around at the resort type of people for more than about 48 hours. We also don't require high end accommodations or amenities. We bought the time share because we wanted a kitchen, laundry, and a gym when we travel plus a "safe neighborhood" which were things VRBO & Air B&B just could not consistently provide. It was the assorted locations via MAX that got me to agree to the purchase. We did not have any trouble booking a vacation week, and we have seen lots of availability at the places we want to visit because we are fortunate to be able to travel at any time of the year. By "downgrading" via MAX it allows our points to stretch, gives us bigger places for less points, expands our choices to more locations, and prevents us from experiencing owning another timeshare in a system with what appears to be high maintenance fees. I know people suggest just owning a TS in each system, but there are good reasons not to do that as well.
Ultimately, like many vacation related discussions here, it just comes back to personal preferences and intentions. Also, like many conversations here, it has been a good discussion and I appreciated reading everyone's comments.
