The number of points needed will vary depending on which adventure you want to go on, the number of people, what time of year, and if you're able to get the early booking discount. If you look at a
point chart, that's the number of points per person.
It will take a lot of points, don't get me wrong. But the trips cost a lot. The other thing that is recommended is to trade out DVC points and then use that money to pay for a cruise or
ABD. We haven't tried that yet (just too busy right now to focus on it), but we'll probably do that in the future.
