I have my next cruise booked with points. The negative to this is that everyone will tell you it is not an economical use of your points. Many DVC owners rent their points on the DISboards and get $10-$11 for them and then pay cash. I looked into this and decided it was just too much trouble for me at that time. I didn't have the cash for the cruise but I was short by about 100 points Of course Disney thought of that and allows you to borrow points from your use year 2 years out for cruises. With points I was booked into a 4A for the 5 of us (3 adults, 2 children) and paid the $95 fee in cash. There wasn't any question as to if we are going on this cruise. It's a chance of a lifetime since we are sailing out of San Juan on the Southern Caribbean cruise and my daughter and her family live in PR so no flight costs for them. The difference in points/cash was about $500 if I could have sold them for $10 a point. But I have 3 DVC contracts and it would have involved multiple use years... I decided to just go for it and I'm happy I did and so are my kids.
Hope this helps. Don't you just love the DISboards! Answers immediately with all the pros and cons to help in your decision making.
