Perk programs are not covered by member dues. So these benefits all exist literally as an incentive for members to purchase direct points.
I often roll my eyes whenever people (non-specifically) gripe about DVC member perks getting worse. Yes things like DME and Extra Magic Hours have changed over the years. But those aren't DVC perks, they were resort benefits offered to all guests. (And DME didn't debut until 2005, so many people were frequent WDW guests before that appeared.)
As for DVC, when we purchased in 2003, the list of discounted restaurants included about 20-25 locations across all WDW. There were modest discounts backstage tours, spa services, waterspouts rentals and mini-golf.
The two things which come to mind which were actually lost over the years were valet parking and the golf membership. Members used to get free valet parking at all deluxe resorts. Gratuity was expected, though members reportedly weren't the best about tipping. And when Disney still owned and operated the golf courses, members could buy an annual discount pass which offered some nice price reduction off the normal rate.
What perks weren't offered prior to 2010-ish? Well, pretty much every other perk we have today including:
- Moonlight Magic
- Private members-only lounges
- Annual pass discount / access to Sorcerer pass
- 20% merchandise discount
- 10% discount at almost every table service restaurant
- Discounts for after hours parties (Disney After Hours, MNSSHP, etc)
- Exclusive photo spots at after hours parties
- Halloween / Christmas / Valentine's Day "meet n treat" events
- Kiosk giveaways like magic band sliders, collectible coins, magnets
DVC is funding all of these items. And they aren't doing it as some magnanimous "thank you" to owners. They exist to help promote new point sales. To sway people to buy into DVC in the first place, and to choose direct over resale.
Some of these perks are also available to groups like Passholders and Disney Visa cardholders. But I expect DVC to continue investing in things like the lounges and Moonlight Magic. Things that they can put in front of prospective members and say "you only get this if you buy from me!"
Are they reason enough to buy points at the Cabins for $200+ apiece vs Hilton Head resale for $70? No, of course not. But the math works differently, depending upon resort, contract duration and the buyers' preferences. And FOMO can be a powerful thing. Skeptics will correctly point out that things like the Sorcerer pass are not guaranteed to exist down the road. But right now, a family of 4 looking to visit enough to justify an annual pass will save about $1800 per year over buying the Incredipass.
