I hope that you who are going in September are indeed the first to stay at Kidani.
Back when Jambo was being refurbished for DVC, it had a September 1 opening. September 1, 2007 to be exact. I made a reservation for that time, thinking I'd be one of the first to stay in Jambo. Well, the construction got ahead of schedule and they opened up units with July and August UY's, and those people, people who purchase after I did, a founding member, got to stay in Jambo first.
I was disappointed, because I was one who purchased first, but could not stay there first. I want to put it out there just in case it happens to you.
