Congrats! While there are no guarantees, Disney at any time of the year is certainly a great start. I've been a member since 2000 and DVC hasn't disapointed me yet!
I bet you are going to have a great trip. We haven't stayed at VWL yet (doing so in Jan) but it looks amazing. Be sure to come back and tell us how it goes.
Try the rib's at whispering canyon. I have dreams about them. Your going to have a great time. If something goes wrong put it behind you and say I'm not going to let it ruin my vacation. It always works for me.
