Walking down the aisle dilemma

So my grandpa is going to walk me down the aisle because he's been more of a father in my life than anyone else, HOWEVER, the last 3 years my step dad has been a huge part of my life. I would like to incorporate him too, if possible. But I'm not sure if I want him to walk me down the aisle as well. I may have them both do it but my question is... If I don't have him walk me too then is there another way I can incorporate him in a special way? He really does mean a lot to me and has done a lot for me so I do want to incorporate him, I just don't know how. Any creative ways?


NOTE: we are NOT having a reception, so no dancing
