Keep in mind if you have an AP/Disney Visa/DVC, the voucher might not be a good deal. I just redid my spread sheet, after 10 mins on the phone with Eric of Disney Dining. Here are the pricing options, for peak times, and the discounts. This includes tax and tip (except for Minnies, I did not include tip.) Note that off peak prices are a few dollars cheaper.
