I booked an OKW GV at the 7 month mark for Sept 5-12 this year. Then this week I started second guessing whether it was the best choice for us, given the ages (4-7) of the 5 grandkids we'll be with. Even though the extra space would have been nice, we changed to a 2 bedroom and studio at Kidani because the kids have stayed there before and loved it. Last year at about the same time we had good luck getting studios at VWL and BWV. We're already planning next year's mid-Sept trip and will again try a 7 month switch.
