Hi,
We own both VI and WM as well as a number of other timeshares. We spend a large part of the year traveling and largely stay in timeshares. We own 451 permanent VI points and 25,000 WM credits.
I may or may not be a good reference for you, as I do not find myself troubled by Worldmark or it's Wyndham management. Yes the sales people are very pushy, but I have obtained a lot of one time WM credits, cash and Wyndham Rewards points that I have made excellent use of from their sales presentations. I have not bought anything from Worldmark since my initial purchase of 7000 credits in 2001.
Unlike WM, VI is controlled by the owners through the VI Trust and a board of owner/directors. In recent years, VI has placed a big emphasis on upgrading their properties. They have also pursued a successful strategy of merging in other small timeshare companies. This expands the owner base and thus more people to cover costs and has added some inventory.
You should be aware of what the history of VI means to current ownership. For a long time, VI sold 25 year and 40 year contracts. As part of that process, they sold "remainder interests" in many of their owned units. That meant that while there will never be more points in the program than properties to satisfy the usage, it isn't guaranteed that all existing properties will always be in the program. They are working through this process and have converted a lot of things to permanent ownership - but not everything. This is an issue with the Hawaii properties more than most others. You can obtain a chart showing what things are permanent and what things have potential end dates. In fact, acknowledging that information is required of any purchase.
You expressed interest specifically in The Emarcadero in Newport, OR. At this time, all of the units there have potential end dates between 2032 and 2038. My personal belief is that they are unlikely to leave the system but it is possible. It appears to me that they are working on the items with the nearest end dates first.
Like every system, some units are more difficult to get. This would include the 3 cabins at The Pines in Sunriver, OR, the penthouse units in a few properties, Marina Inn in Oceanside, CA and some dates in Hawaii.
I am a planner and a timeshare geek. I have no complaints whatsoever about booking what I want the vast majority of the time. I am also totally happy with the units that we use. They are always very clean and well furnished. As noted, at some locations VI does not manage the property nor own all of the units. However, VI does manage the reservation process for all locations and has a good working relationship with the properties they do not manage.
VI was our first timeshare purchase over 30 years ago and starting with 81 every other year points. We have continued to buy more over the years. I am actually looking to find a contract with 8 to 12 years left to add some points during our major travel years ahead.
Continue to do your research and see what you think. Do be aware, that units at The Embarcadero do tend to involve a fair number of stairs.
