DVC is a timeshare - "upgrades" are not available with DVC points reservations as may be case with regular cash hotel reservations. A reserved villa would have to be taken out of service for emergency maintenance or some other unforeseen situation and no other villa of same size available in order to get upgraded - rarely happens.
If your points are transferrable than a transfer of points to another
DVC member ( transfers are not possible with non-members )
is usually much less trouble / worries
than making a reservation with your points for either a member or non-member
to rent from you. You are allowed to make 1 transfer per year of either points
out of your DVC account or of points into your DVC account. If you transfer
points out the other DVC member handles everything from that point on ( ie
making reservations using those transferred points ); if you transfer points
into your account you handle making reservations or banking for future use
those points ( transferred points cannot be taken back by the transferring
member ).
In order to be transferrable, points must be from the
Current Use Year, not points that have been banked &/or borrowed and
each member participating in the transfer transaction must not have
already had a transfer made during that year.
CONGRATULATIONS on your new membership & WELCOME HOME
