What a heated topic!
First, let me say I'm a little disappointed in some of the rudeness displayed in several of these replies. Opinions are like belly buttons, everybody has one and it is really disconcerting to see how disrespectful some people can be.
From my reading, it does seem to be clearly against the bylaws to run a business renting points (that commercial clause), although Disney has also clearly left the ability for individual owners to rent their points when they can't use them open. It seems like some
DVC'ers are walking a fine line there. Not all rentals are bad, but there is a line there that might be construed as breaking the rules if you're really just treating this as a business.
I know I like the idea that I can rent out extra points if I need to (sometimes you end up with just a few that will expire before your next trip and it's nice that you don't have to just lose them.) Also, I know we'll be skipping the years I'm pregnant or have a very tiny baby (Some of you hardy souls may be up for it, but not this mama

) I would not be involved in price-fixing for renting, however, I would certainy look at what the market rates were before renting and since I would only have a few points I'd be looking for another member who needed just a few to round out their reservation.
The Sun-Thu debate eludes me I must admit. It seems that if DVC did decide to reallocate the points that would be to the detriment of those who currently do the Su-Th ressies and would likely not affect those who book full weeks as the pints would be equally distributed. Those who book weekends would actually benefit. Am I missing something here?
Being in the midwest I can tell you that we are likely to do a Su-Th ressie if we drive simply because it take 2 days to get there and we'd leave Fri night so as to have the last Sunday of vacation week to prepare to go back to work (cry, gnash teeth, moan over how fast the week went, etc.

) Sorry if this bothers some, but part of the attraction to DVC as opposed to other timeshares is the flexibility and the fact that we don't HAVE to book full weeks. Just something to keep in mind when ranting about people coming in on Sunday.
Thanks for all the thoughts! I really enjoy reading everyone's posts on hear and I certainly learn a lot each time.
