I will say that I rent points because I bought too many for our current needs (yes, it is possible to have too many points
The final decision for us to finally buy into DVC after 4 years is knowing the ability to rent out additional points when we won't use them. We don't want to feel forced to take WDW vacations just because we don't want to waste the points.
I feel the flexibility also supports the strong resale market demand for these points. I use the point rental to offset some of our vacation costs, and also I use it for other vacation spots. Like some other posters said, it is too expensive to exchange out. I always feel bad to see how little people get when trying to rent out their reservation points. I will definately rent out my points for my cruises and other destinations, without worring about cancellations (with young kids, you never know) and ending up with these points that I can't use.
I disagree with the weekday vs the weekend thing. Even as a member, I have a hard time justifying staying for the weekends, maybe time will help. The only trip that I am staying through the entire week is for my Xmas reunion trip because I don't want my family members to go through the trouble to move. So if I would only stay for weekdays, why should I expect my renters want to stay for the weekends. I always offer that as an option, but most people would choose to stay somewhere else.
As far as renting out rooms vs. reservations, I feel it is up to personal preference. I like to rent out reservations so that I have control of the timing of the reservation and the point requirements due to my point status and the use year. I make reservations in the same process as others.
Lastly, I don't feel I am profitting from renting. Everyone can determine how much their points are worth. However, I can't figure out at what point someone can profit from this. Does it have to offset your purchase price? That would take YEARS with the dues, time value of money and consistent renting.
We LOVE WDW and we will be vacationing there for many many years to come. I don't feel that I am doing anything bad from renting. Actually I rent my points to/from people and I truly enjoy the process and meeting people I otherwise would not have met.
I never thought that I would buy a timeshare and this may be the only one that I will ever own, because of the quality of its resorts and its flexibility.
I love this board and frequent it daily. I would hate to be viewed as doing something wrong
