My husband and I did just this back in 2017. We went to a presentation, signed for 2000 (or 2200, don't remember) and the next day, in whatever pen or marker I had in the car and a blank piece of torn paper, we wrote that we were rescinding, signed and done. They didn't ask for the book of resorts/points listings back, which was a good thing since we left it in the resort
. So, once we realized we still had the book, we sat down and looked at how many nights the points cost would be in most of the places we wanted to go with the points we were looking to buy and realized that it would really only be 5 nights (2 bedroom).
Back then, during the presentation, the sales lady slipped (at least I think it was a slip) and said something about Marriott reselling legacy weeks. Another thing I didn't realize until late that night after we signed. Like, an aha moment. In the morning, I looked it up and at that time Marriott had a resale week webpage. I found the week we wanted in the resort we wanted. The points would have cost somewhere around $29,000 or $30,000 (maybe a few thousand less as I do remember some sort of bonus to buy before we left, there was a "catch" to that but don't remember what). The week was 1/5 of that. We chose to just go directly through Marriott so no hold up, less fees, etc. We probably would have gotten our week for less on the open resale market, but it was quick, easy and we're very very very happy with our purchase. Can't wait to get back there asap.
Good luck with your new purchases everyone! Enjoy every vacation! For us, no regrets. At this point in our lives, we actually like our Marriott week more than our 385 DVC points!
Have a great day!
