Call your guide & ask to be placed on the waiting list for OKW add on's.... they do have a list, because just last week we were able to add on at BWV's through Disney... We paid the 75 per point, but we could have done MB for 5.00 a point...
You won't find many 50 point add on's in the market & when you do, they go for pretty close to Disney's selling price & usually they don't have points til the following year!
