I would have agreed with you a year ago. We have been going to the same places (plus NYC) and would like something new. Now with Diamond adding properties to HGVC I am excited about new locations e.g. Lake Tahoe, Poipu, Maui (KBC on Kaanapali), Cabo Azul, Palm Desert, Whistler, Sedona.
In a recent presentation, sales reps indicated that we at the highest level of the system so will have access to Diamond properties (bHC and/or HGV Club - they didn't specify and we own both). Whereas Diamond members will be urged to upgrade for HGV access. If true, we will be buying more points and will not add to our Marriott/Vistana holdings because we like the points flexibility, and better management of MF of HGVC; Marriott/Vistana MF is 1.5 to 2x more expensive, the MVC system is less flexible and available for high-end units which tend to get rented out or used by owners (or not enrolled so will never be available), Vistana has points but has significantly fewer locations than HGV. With HGV I can use points to get consistent access to penthouses and oceanfront if desired during peak season. Not confident that I can do the same with MVC with only 60% of units enrolled in the points program.
Besides to get access to more MVC locations and points we are not willing to pay $10 - $30k to enroll our resale in MVC when we already get access to flexible points via HGVC. and Vistana. Waiting on announcements in 2022 before acting because...well...they are reps so who knows what this or the new MVC program will entail.
