I think Odin probably objected to Thor wanting to "chase a skirt" with his feelings toward a woman developed only during the course of 2-3 days. But as Thor said to Loki, that Midgard/Earth is the realm that he swore to protect, it makes more sense that he'd be able to convince All-Father Odin to use his energy and get him there.
