Although it does not drop you off in front of the hotel, it drops you off at the express bus terminal which is connected to the hotel. There is no need to walk on the street. Once you arrive, go inside the express bus terminal, take escalator up and follow the sign. You will need to pass through some shops. Look for another escalator near Uniqlo. That escalator will take you up to JW Marriott.
