You can enter the check-in area before the 3 hours very easily with a doctored boarding pass - but you won't be able to check-in and pass security to enter the lounge. There are arrivals lounges but you can't enter the arrivals area from the departure hall.

Best would be to have a later dinner at the Marriott and/or use the gym. I am quite sure they will let you use the shower/changing room if needed.
