Most here will agree that the best economic value of
DVC is staying at a DVC resort.
Opinions on the value of the cruise option vary.
In most cases (especially if you book far in advance), you will come out ahead if you rent your DVC points and use the proceeds to pay cash for the cruise. The average rental rate is $10/point. Some get less and some get more.
Some other factors to consider:
Renting points requires a bit of risk taking and entails work on the part of the owner. It may be time consuming, especially for a beginner.
The number of points required to cruise can go up (and has) on an annual basis. This is not true of the points required to stay at a DVC resort.
You may only book a cruise 11 months in advance if you are paying with points. Thus the most desirable cabins may be gone by the time you can make your reservation. Not all cabin categories are available for points. Sometimes the special "credits" and "perks" available to cash-paying cruisers are not available to those who book with points.
If you have to cancel a cruise that was booked with points, the points from the cancelled reservation may not be used to book a DVC resort or an exchange through II. They may only be used to book the non-DVC options in the Diseny Collection (which includes
DCL), the Adventurer Collection or the Conceirge Collection.
