The antonyms for the word "more vacated" would be "less occupied" or "more filled." Vacated means empty or unoccupied, so the opposite would be occupied or filled. If something is "more vacated," it means that it has been emptied out or cleared to a greater extent. Therefore, the opposite phrase, "less occupied," would imply that something is still in use or has not been emptied completely. Alternatively, "more filled" suggests that something has been populated or filled to a greater degree. It could be a room with more furniture or a container with more objects inside.
