you'll need some help pulling this off but we went last August and our daughters boyfriend proposed to her during the fireworks at MK and asked if we'd help. I called our hotel and there wasn't in advance we had to go to the photo pass people (building to the right when you get into the park) we had to preform some evasive maneuvers to get away from the kids. He wanted to do it in front of the castle during the fireworks but they said they normally don't take pictures during the fireworks, they stop about 45 minutes before and don't resume again for 30-45 minutes but they said they could see what they could do. He talked to his supervisor and she texted back and forth with my wife to get it all setup for us to be on main street about 5-10 minutes before the fireworks. right before they started the supervisor came up to us and said they were trying out new camera settings and asked if we wanted to be the test subjects. Never turning down a photo op our daughter jumped at it. The photographer was strictly there for us and took pics of them the whole time. It was amazing and they didn't charge anything for it. Not sure if you'll have help there but if you do and the castle or MK means anything to you it was a pretty cool experience.
