VI is Good
We have owned in VI since 1989 when we bought the smallest every other year package. We have bought more several times from the developer and also bought on ebay. We now have over 400 points (you might think of that as 4 weeks or so). VI was among the first to come out with the points program and it provides tons of flexibility.
We now have Platinum status which gives us a lot of great perks. Be aware, however, that points purchased now on the secondary market will not qualify you for any kind of premium status.
Now we use a lot of points at once for penthouses, etc. When we retire we plan to do more time in smaller units.
Like any program, the point is to use it. So make sure there are places you want to go in the VI program. We now live in Sacramento so go to Lake Tahoe a LOT but have stayed in many of the resorts over the years.
All of the properties are in the Owners Trust and thus are not subject to bankruptcy of the management company, etc as they are owned free and clear by the owners.
One more thing. VI used to sell packages for 25 or 40 years. They are trying to get people to convert to perpetual. If you buy on the secondary market be sure you know if the points have an end date or if they are perpetual. Also, be sure you understands that this also means some properties (especially in Hawaii) will eventually fall out of the program if VI is not able to negotiate purchase of the "remainders".
So...thumbs up for VI.
