I frankly don't blame the Aspen Highlands owners. Maui, Bachelor Gulch, Jupiter, Kauai Lagoons, and even San Francisco prove that Ritz Carlton Club is a failed business model. That really sucks for the Ritz owners who paid so much money. Some of these owners (Bachelor Gulch, Jupiter, etc) collectively found an exit path that gave them more control over their own destiny. Unfortunately, the Aspen Highlands owners are stuck with fewer options because Marriott owns most of the inventory and thus controls most of the voting power over decisions.
The courts will decide if their complaints have legal merit, but I sympathize with these owners. If I paid big bucks for the promise of exclusive access to luxury properties, I would be upset too at my diminished value and reduced options. That sucks, but that's life. There are countless examples of real estate investments that don't always work out as planned. Through the Destinations Club, at least Aspen Highlands has financial viability which allows these owner to still enjoy the beauty of their home resort. The same was not true for Maui.
