I wouldn't be surprised if
DVC figured out a way to offer the concierge-exclusive events to
any DVC members staying at the resort. That would certainly help address much of the member frustration over the limited supply of concierge rooms.
The only drawback I can see is the likely backlash from cash guests. Of course, DVC members pay a whole lot more than even those paying concierge rooms, so some of the complaints would be baseless. But I'm sure there would be more than a few hearty debates on the topic.
If they did this they would almost certainly have to expand the number of days it is currently offered. Perhaps they could keep the current schedule for concierge guests and add a couple of other days during the week just for DVC.
Anyway, don't take this as a rumor...just my own speculation. If the Sunrise Safari were offered to all DVC members staying at AKV, I think it would alleviate a lot of the booking issues that are destined to occur with barely 1% of the resort's rooms in the Concierge class.
