We honeymooned in Disney World in December, 2006. While we got lots of "Congratulations" from cast members, other perks were few and far between.
No room upgrades, no free meals or snacks, no rides in the parade (though we did see one honeymooning couple riding in the MK parade).
On the night we ate at Tony's our table was decorated with streamers and Mickey confetti. And at Boma, we received a special dessert plate of candies and truffles made by the chefs.
We made sure our ADR's said we were honeymooning and wore the buttons saying the same.
I just don't want you to expect a lot of perks and then be disappointed. We had a great time and were able to create a little Disney magic of our own along the way. My DH is an avid pin collector and gave away several pins to kids who were just starting their own collection. Those moments and the looks on those kids' faces were what really made our honeymoon special!
