Meridian is very close to the port. I would guess only 2-3 minutes by car.

If you are taking the ferry over from Sorong, the dock to the hotel is 200-300 meters away. Please note, if you use Google map, you will think you need to walk 500-600 meters since it doesn't realize there is a boardwalk. After crossing under the large welcome arch, turn right on the covered boardwalk. No signs, but it's a good quality path
