Yes - AKV is wonderful. We stayed there in January in the Jambo house. We really enjoyed it. The resort is gorgeous.
As for the 8th, you could book a back up room through Disney and we can wait list that night. If the wait list comes through - you cancel the Disney direct reservation. If it does not come through, you would at least have a room. You would have to switch rooms, but it would still work out.
I have sent you an email as well. Just get back to me when you can. I understand the hesitation. It is a big chunk of change (but a big savings over Disney direct)...so, think about it and let me know.
Have a great night.
Sue
