I've been on this waitlist for a year now, if I'm not mistaken, by exchanging just one point. The waitlist was for ticket purchases only, not for a Disney cruise, hehe. It turned out I didn't use the waitlist because I had other plans. But I'll give it a rating 🙂 because it's convenient, you can waitlist well in advance, and you'll get 1,000 points for leaving a review.
