How do I tell my Dad I don't want to go over there?

My dad wants to pick me up today until Sunday. I don't want to stay that long let alone at all. I don't want to hurt his feelings either, but he isn't much of a father. He barely sees me, but I'm a pushover. How do I tell him I don't want to go over with out hurting his feelings, or what's a good excuse. Lol. I can shorten it until Friday by having my mom say she needs me for something, but I don't know about anything else. Help soon please, I have to go when he wakes up which is usually about noon.
