Sorry to pick this one post.
One of the first economic terms learned in a 101 or 102 class is there is no such thing as free. Someone is paying.
Commercial has no specific definition other than engaged in commerce.
Renting to cover ones dues is just not a good point to justify non commercial as it can easily be proven it is.
"Personal use may include enjoying the benefits of a
DVC Membership with family or allowing use of any reserved Vacation Home to friends and family on occasion. Additionally, personal use means that the member does not regularly or frequently rent/sell reservations booked using their membership."
This is very intentional wording covering that was a reservation for my friend or 99th cousin will not work. Renting to cover dues is 100% regular renting. Then adds Frequent... Frequency is simply a pattern like I use all my points one year the next I rent all my points. Any renting over any period that occurs more than once......
If you rented once in 3 years then 7 years later then 2 years after that this is not frequent. In the same if you make reservations for family or friends for the exact same time you are there or your child, brother, sister etc.....
While I would love to say X should be allowed it is very apparent DVC intends to and likely will make examples of ? Before you say X should be ok.... I would seriously consider how one can defend the broad yet some specific working and this is done with the reason of we can defend canceling very easily.... Now up to the owner to prove otherwise with 99% in a court room with $$$$$$ Lawyers (and I do mean you better shell out for the best).
