You can rent DVC points as a one-off - you would just see how many points you needed for where you wanted to stay, then look for somebody who had points to rent at that resort - either on the 'for rent' forum here on the DIS or through a broker like David's Vacation Club Rentals. You would need to fully understand the nuances of renting, such as you would be unlikely to get any refund if you cancelled etc. however it can be a great way of getting 'cheap' deluxe accommodation. Feel free to PM me if you have any specific questions or want to know more - or, alternatively, we have a DVC board here in the UK forums, if you want to ask more questions.
