There are so many porters that can quickly get your bags, we never do the express. Even once we got off at 7:30, grabbed a porter, he hailed a cab to rental car and we made it Universal Parking lot by 9:10am. We have a 12:10 flight next month too. I also have heard buses will leave when they are full, so we plan on being off 8:15-8:30am We do have to check bags with Southwest.
