I have not looked at the site rules in a long time but, unless they have changed, you cannot offer a confirmed reservation time for rent unless you are something like only 30 days or less out. In other words, you can do it only if you are already in a distressed situtation where you may lose your points because you need to cancel.
As to what you describe, reserving high demand times and then trying to rent them, it is an activity you sometimes see on other boards like eBay. As to views on the issue, you will likely find a large number that will despise you if you do it and refer to it as "predatory reserving."
. The reason is historical. By the mid-2000's online rentals of DVC timeshares had become the normal and easiest way to rent. At the time, the rules allowed unlimited number of transfers per year, although limited to one way (you could either transfer in during the year or transfer out an unlimited number of times, but not both). Moreover, anyone could become an associate member on an unlimited number of memberships and make reservations using those memberships. Any inidividual could own up to 2,000 points per resort and 5,000 all resorts and a gourp onf individuals could get together and own a lot more than that as long as points were bought separately by each member of the group.
What happened is that
DVC rentals were basically taken over by some groups of professional renters who were in the business of renting points. There were partner groups that purchased large amounts of points. They also heavily advertised seeking transfers of points to them and would actively solicit owners who wanted to do some renting to make them associate members. They then used many of the points they had control of to book, at exactly 11 months out, huge numbers of reservations for highly sought after rooms and reservation times such as Christmas, Thanskgiving and other holidays and then advertised their reservations for rent in numerous places. Many other owners found themselves blocked out from reserving the desired times.
The cacaphony of complaints were eventually heard by Disney. Prohibited by the offical documents is to rent for commercial purposes, a vague term defined as including repeated renting from which Disney, in its discretion, can conclude shows you are a commercial enterprise. Disney created three rules to attack the professional renters: (a) it adopted a rule that said that any member who made more than 20 reservations in one year will be presumed to be in violation of the commercial purposes rule and would be prohibited from making additonal reserations unless the member could show none were rentals; (b) it abolished the unlimited transfer rule and adopted the single transfer per year rule that exists now (and which was actually the original DVC rule on transfers); and (c) it adopted a rule limiting any person to being an associate member on no more than four memberships.
That did not resolve the professional renter problem completely but it certainly took the wind out of their sails and greatly reduced predatory renting. This site adopted rules limiting who could offer rentals and how it could be done, including prohibiting predatory reservations by limiting your ability to rent a confirmed reservation to a short period before date of arrival.
In other words, I would not expect to find large numbers, particularly of veterans, on these boards who would think that your proposal is something members should really do.
