Just some random views most of which I posted elsewhere but thought I add here:
1. When you purchase DVC, you buy a real estate interest in a "unit." A unit is usually a group of rooms and the purchase is similar to purchasing a condominium. The rooms are called "vacation homes" in the official documents to distinguish them from the unit and the actual real estate purchase you make. Points are deemed to be symbols that represent your real estate interest. The documents declare that points have no monetary value. Thus, though everyone perceives their points have value, from a legal standpoint, they have none. It is the real estate interest itself that has value. To maintain that legal lack of any monetary value in points, the documents also declare that you cannot transfer points for value, in the form of money or otherwise. In other words, you cannot transfer points for money because such an act would be giving points a monetary value when they are deemed to have none. Have that is all that is probited -- the act of transfering points for money. That does not prohibit rentals.
2. The documents declare that you can rent or lease any portion of your real estate interest subject to the rule against doing so for a "comercial purpose" and a commercial purpose can include a pattern of rental activity from which DVC could conclude that you are acting as a "commercial enterprise." Recently DVC adopted the 20 reservation rule creating a presumption that you are violating the commercial purpose rule if you make more than 20 reservations per year. That was an interpretive rule (and one allowed if it is reasonable and not arbitrary to enforce the commercial purpose rule, which it would likely be found to be) to give DVC some objective test that DVC personnel (including those rather low paid persons who answer the phone and control our lives) could apply without trying figure out for themselves what is meant by commercial purpose. It also gives DVC something it can put into the computer and the computer can spit out a deviation report on a member when the count rule is broken. You can't put the words "commercial purpose" into the computer and expect it to tell you anything. Note, it only creates a presumption so you can still try to show to them when you make that 21st reservation that you really haven't been engaging in a pattern of rental activity. That fairly high number of 20 and the lack of an absolute cut-off at 20, which leaves you the opportunity to explain otherwise and still go over 20, is actually what keeps the rule from ever being declared unreasonable or arbitrary. The number is high enough that it unlikely will effect many people. The new interpretative rule also restates that you cannot transfer points for value
3. DVC also recently adopted the one transfer rule. That is actually not a new rule. From the start of DVC and then for most of the years of its existence, the rule was that you could make only one transfer per year. The rule allowing multiple transfers was a change made about four years ago and thus all they have done now is go back to the old rule.
4. DVC cannot pass rules that alter material rights granted under the contracts and disclosure documents. For example, they can't change the rules to say you can only use your points in your use year month or that it can sell more points than it would take to fill the resort for a year. By law, renting is deemed a material provision of a timeshare but restrictions are allowed. Whether they could prohibit renting all together is subject to question, but the one thing they must do if they want to restrict renting at all is put any restrictions in the disclosure documents that you receive when you buy. If the rental restriction is not in the documents you received when you bought, they can't change it for you (or anyone else who received the same documents when they bought). The new rules, however, are not really a change. The "commerical purpose" rule is still the same. The new rules are interpretative. Also note, though in a few places in the offical documents, DVC spouts the right, in its absolute discretion, to change certain rules, that is inapplcable to any material rights. Also, it is a facade. DVC management is, by law, a fiduciary of its members. It must act in making any changes to rules or regulations in the best interests of the members and cannot base changes on what would be favorable to Disney as opposed to members. That doesn't mean all members must like any chages made but it does mean that any changes must be for a reason that is considered to be in the best interests of the members as a whole.
5. Why the 20 reservation rule and reversion back to one transfer per use year? The internet is partly to blame. Without it, there would be no real rental market and thus no reason to be concerned about rentals. What was going on is that a market developed and there was at least the perception that there were a number who had essentially gone into the business of renting DVC, buying large numbers of points (circumventing total point limits of 2,000 per resort, 5,000 total, by having more than one person purchase) and renting all the time. Some proof of the truth of that perception was at least that there appeared to be persons on the internet who were always offering rentals including on ebay and the rent portion of this site and there were many rental offers for hard to get times like Christmas time, meaning the renter was probably making numerous reservations for hard to get times at 11 months out and then renting that time. (Even this site recently changed its rules for posting rentals by prohibiting such if you attempt to post already existing reservations for a specific time far in advance of that time).
6. That perceived or real rental activity caused many to complain, particularly the activity of getting hard to get times and renting them out. For a long time DVC did nothing and possibly for a long time the problem was more of a perception rather than real problem. But at some point fairly recently, DVC must have concluded that it had a problem that needed some action. Some here have expressed the belief that DVC's latest rules were put into effect to protect Disney's own rental market. I think not. In any event, I am certain DVC would never admit that was the purpose or that it did it for any reason except to act in the best interests of the members. If it said it took the recent action to protect Disney's own rental interests, it would be conceding that it breached its fiduciary obligations by acting in Disney's own interest rather than the interests of the members, subjecting it to the risk that any such rules would be voided and a possible risk of fines. In other words, we should assume that the new rules are designed to address the problem created by members who apparently are in the business of renting and thus violating the rule against a "commercial purpose" and that the problem was noticeable enough that it was effecting other members ability to reserve rooms.
7. So basically what we have now is a DVC that is actually trying to enforce the "commercial purpose" prohibition. In that vein, the enforcement ultimately goes through rather low paid MS representatives who handle reservations. What we have is the usual problem that creates. Those MS personnel have been told of the new rules and that DVC is trying to crack down on commercial renters. Most of them don't really understand all the issues and we will have situations where they start doing things that are "creative" but incorrect.
8. Will the new rules actually rectify any rental problem that they are desigend to address? I don't know for sure. The one transfer rule (the old one now new again) does help minimize that form of rental which can be done without the risk of cancellation. The 20 reservation rule probably will have some impact but it depends on how many different persons are in one group of renters. Also, the rule does not actually address the thing that was most complained about -- people making ressies for prime times 11 months out so they can rent it. Moreover, it could even generate more rental activity. By negative inference the rule tells people they can rent as long as they don't excede 20 a year and thus those who rented somewhat could actually became a little more active. In any event, they give DVC what I think it mainly wanted, an objective test that would pass any legal challenge and it shows to members DVC is taking action for what was preceived to be problem of monumental proportions.
