Our niece got married at WDW on 11/11/11 at 11:11. While she didn't do the wedding chapel she did have a view of the castle from the Marina at the GF. It was a small wedding and the Disney wedding planners worked with her to make sure she got everything she wanted. There was some sort of snafu, though I don't remember what it was, that got their wedding night hotel comped. The reception was in the Living Seas and it was spectacular. Mickey and Minnie showed up. There was a diver that came up behind them in the aquarium with a sign that I never did see. I think it bore a congratulatory message though.
