Can Marriott arrive early?

Of course. The general hotel reservation is from noon 12 to noon the next day 12. You can arrive at Marriott Hotel in advance. If you arrive before noon 12, you need to pay an extra day's fee or stay in an hourly room, so it is ok to arrive early, but you need to pay extra. If you arrive at the hotel in advance, you can contact through the APP or make an appointment by phone, which can better provide corresponding services.
