Ceremony Entrance to be Hidden

I am getting married at my grandmother's house in front of her house. I want the dramatic moment of the doors opening and here comes the bride playing (I had doors built to be able to do this), my question is.... How do I walk from behind the house where I will be hiding, to the front without anyone seeing me??? My dad said a horse drawn carriage, but I don't know if I'm THAT extra. I am a "princess" type, but its kinda extreme lol. Any ideas?? My fiance said he'd build a pallet wall, but that would be a lot of area to hide and a heavy wall.
