I would look at the top three websites mentioned above AND CALL them all... 2 of our 3 resales never made it to the web page, so if I hadnt called and told Jaki what we were looking for (# of points, resort, UY) I would have missed out on a fully loaded BWV contract for 64 pp (before the huge ROFR started, thank goodness)
We used Jaki 3 times and it went very well, but I would still Shop around.
