I don't really see what the point is in getting married to someone you don't want to live with. You don't really believe in fidelity as you claim to have an open arrangement. You don't want to establish a real life with him if you are so set on living life your own way because you don't want to share your space or in any way change your life. You don't really plan even to have an actual wedding, but instead a hand fasting ceremony. If you just want to go to DisneyWorld, just take a vacation together. I just don't hear a great deal of commitment to establishing a new life with this man as a married couple.
