Wedding and Father Issues

My Fiance and I want to just go to the court house and get married, then have a reception/party. (I don't really see the point in paying for a dress and all that extra stuff to wear for a few hours. Then have it sit in my closet forever or sell it for half of what I paid for it😂) But the only problem is, my dad wants to walk me down the isle. I'm his oldest child and only biological daughter. (I have a step sister, but I don't think it's the same thing.) What do I do?😭💯 My dad is my best friend and I don't want to hurt his feelings.
