Here are some examples for 2005:
3-Night point range: 71-263 points per an adult (cheap season to high, CAT 11-4)
4-Night point range: 87-282
7-Night Eastern: 141-455
7-Night Western: 149-456
Cruising on points is not the best value, but it does save on the inconvenience of renting your points out. Some will rent their points to pay the cruise and then have extra points or more money left over. Let us know if you have other questions!
