Until we actually arrived Monterey area, we have not decided to visit Point Lobos. And are we glad that we decided to visit. Even though the morning we visited was extremely foggy and the visibility was low. the rocky sea shore was magnificent and cannot be hidden from sight.
If you are considering including Point Lobos into your visiting plan, my suggestion is to arrive the park gate as early in the morning as possible. The park gate opens at 8AM. But at that time there’d already be a long line of vehicles waiting stretching out onto the highway. More importantly, once you have entered the park, there is very limited parking capacity among the existing lots. So the options are: 1. you wake up very early in the morning to find a relatively good parking situation inside the park, then hike around, or, 2. you get there later in the day but you’ll most likely have to park on the highway (you’ll see what I mean if you do that) then hike into the park. 
The entire park is just the Lobos Peninsula, which truthfully is not more than an hour hike from one end to another. So most of the time you should be able to complete the walk within an hour or two, plus all the time you stop and take photos off course.
The day eventually turned sunny after around 10AM and we get to see the rocky coast well lit to create some beautiful contrasts.
