I got engaged in front of the Magic Kingdom. My (now) fiance, my sister, and her fiance were going to go to MK after Fantasmic in August of 2000, but we arrived at closing time. As it was our last night there, I HAD to do it then...so we were sitting on a bench and I said, "I wanted to do this right, but...", got down on one knee, and proposed.....not the most romantic thing in the world....but she was happy and I was happy so that is all that matters, right?
Epilogue: I found out about 6 months later that my mom outed me to my fiance before we left for WDW and my fiance was expecting the question the whole time...needless to say that I was not happy about it, but what are you going to do, right?
