You can do this by sleeping in town or at the airport. It depends in part on the time zone that you are coming from, i.e. will you be sleepy when you land. You could do as suggested above or stay at the airport hotel, get up early and jump on the Maglev, visit for a while and get the Maglev back - all without luggage.
