DH and I honeymooned in Disney 3 years ago and we bought the ears in DTD our first night there. We didn't wear them every day but the days we did...whoa! We got some awesome perks! First day in MK, cast member at entrance told us to make a reservation for dinner at Cinderella's Castle (that was before it became all-u-can eat dining). She said they would "fit us in."
It was awesome! Table was decorated with confetti, our food order was pushed ahead of everyone elses and the best part....they came out with a box and said it was a wedding gift from the Castle. They were beautiful champagne flutes with "Cinderella's Royal Table" on them. Awesome! We received lots more perks including fast passes and front row seats at Beauty and the Beast show, where we were seranaded by their pre-show quartet. They also gave us a free CD.
Get the ears, you will love it!
