If you spoke to Susan, then you have the reward! It was a big hassle to cut out all the proofs, but they were rather quick in coming back with an answer as soon as they received it (the same day). BTW, if you went to the Disney Movie Rewards website, there was a way to print out your entire history of redeeming points. That is what I did and it was a big help (I just taped a proof right next to the points that I redeemed). Anything that I could not come up with (which was about 8 DVDs), I just provided them with an explanation in a cover letter that I attached.
Susan is the one that coordinates the tour and, if I understood her correctly, is someone that goes with you.
We are a bit more flexible in our dates since we live about 30 minutes north of the Disney studios. We are going to give her a couple of dates in April that are within my two daughters' Spring Break schedule, and also provide her with some dates in the summer if that does not work out.
Good luck and keep me posted.
