We stayed at AKL for our honeymoon - nothing extra in the hotel as such, just a great hotel!
Out in the parks/restaurants - loads of little things!
On entering Epcot, we got the phone call from Mickey/Minnie, then got it 3 more times. Had to look pleased and surprised each time!
Free desserts at several locations, free meal and margaritas at Cantina de San Angel, a few "magical memories" with Cast Members at different locations, we were mentioned by the singers at the America pavilion in World Showcase, fastpasses galore. We also got into the wine room (think thats the one) in California Grill, which was really nice.
Other than that, many, many,
many congratulations from Cast Members and guests. This all happened because we had our "Just Married" pins on.
I am sure you will have a great time!
