If I were MVC, first I would create the MVC charts for the Vistana properties and overlay the seasons onto them.
I would then match up the unit type owned in Vistana to the current MVC system. So if you own WKOVR, WKOVRN or Nanea, I would give the owners points based on what they own: IV, OV or OF.
However, I would not assume the current view types in Vistana will be identical in MVC, regardless of how Vistana categorizes them. For example, I might make WKOVR OF worth more points than WKOVRN OF because the WKOVR OF has real oceanfront views and the availabilitry is already limited and hard to book into.
I would also assume Harborside and St John will be premium products in MVC and get more point value relative to what they get now in Vistana.
I would look at where MVC already has resorts to get an idea of how they might value the Vistana units for staying with DPs. For example, MVC can use the current Hawaii, Orlando, Palm Desert, etc charts to get an idea of how they may values a current Vistana resort.
If I were Marriott, I would also look at MFs to get an idea of which resorts are premium products in terms of the MF per week. The more expensive resorts would get more points than the less expensive resorts to make the values match up in DPs.
I would also look at where demand is high and where it is low and give more DOs to the high demand resorts.
Obviously they will not take away the ability to book your week. ButI suspect they will get rid of SOs entirely because they will have converted all Vistana owners into MVC.
I also think they will need to assign a DP value to each week that may or may not be better than if you used your underlying week. For example, in the current MVC system, there is what folks have called breakage so I assume there will be breakage for the Vistana resorts as they get integrated into MVC DP charts.
It is possible that MVC will grandfather in Vistana owners at a better DP amount that we expect. This would make sense if they want to make it more expensive for everyone to use DPs at the Vistana resorts. This is what Hyatt did a few years ago when they converted more Key West weeks to diamond season. The existing owners of those weeks were winners but Hyatt also won by making it more weeks into diamond weeks, hence they were more expensive for everyone else to use points for.
Of course, I am not MVC and I am not thinking through the details of how what I outlines above might work. I think some people will be happy and some will not be but I suspect MVC will design a new system that will make the vast majority of their members happy.
