I own resale only with no perks... I would buy direct for Blue Card IF they had a more reasonable buy in. At 100+ points buy in with current resort offerings I could buy 200 points resale for the same exact money, even at Aulani which is a current offering! For double the points, the benefits are not worth it to me.
Perhaps with the new Cali offering coming up, I will buy direct there, since Cali points are not as discounted on the resale market.
