is it only worthwhile if you go for more than once a year? sorry for all the questions but I'm very confused
Certainly not Carol. With banking and borrowing of points, in theory ( if you were VERY organised), you could arrange it so you only went once every 3 years and didn't lose any points. In practice trips every other year would be much more workable.
With banking and borrowing, if you don't/can't use your points for one year you can "bank" that years points until the next year. You do have to do this by a certain date depending on your use year. Alternatively you can borrow the next years points and bring them into this use year to use. So for example you have 150 points for your use year starting july 2005. You know you're not going at all this year so you bank all 150 points by the stipulated date. You would then have 300 points ( 150 from 2005 and 150 from 2006) available to be used from July 2006 . If you decided to have a MASSIVE holiday in Xmas 2006 you could use all of those 300 points AND if you needed them 150 points from the use year that starts July 2007. It would mean you couldn't take any more stays on points until July 2007 , but you would have made only one trip in 3 years and not had to lose any of your points. More usual would be to use points from 2 years, that is really easy to do and to plan. Getting 3 years worth lined up, banked and available to borrow requireds the owner to be "on the ball" with their dates.
Flights can still be expensive, particularly if you're tied into school vacation times, but even so again if you're flexible, organized and don't mind a little inconvenience ( like flying into Tampa or Miami and driving up) then it's possible to get flights at a reasonable rate. If you have your accommodation paid for (don't forget you have the access to cooking/fridge facilities that DVC rooms offer) it's possible to have a great vacation in WDW for relatively few $$$ , if you're having a tough year financially you may have to limit the trips to the theme parks a little and be choosey over when and where you eat, but the DVC resorts offer plenty of free/cheap recreation so that you can have a top qualitity experience on a shoe string if that proves necessary.
For many people it comes down to a question of priorities, if having a top quality wonderful vacation on a regular basis is something that's important to a family/individual then DVC can often help to achieve that. Many people like to buy into DVC because they know UNLESS they take a proactive step that MAKES themselves commit to the idea they know that there is a good chance that, even with the best intentions, the money needed to fulfil their vacation dreams will leak away through their fingers.
Carol, please don't worry about asking questions, there's no such thing as a daft question. It's not an easy concept to get your head around ( I found it particularly vexing not to be able to find "the catch" , because I was convinced the deal was just too good to be true. After 13 years I'm still looking for the catch). It's people asking questions that are the life blood of these boards, without questions they would wither and die.
