OPIC Script Grammer check (Topic_ spare time)

Question : You might do some fun or interesting things in your free time. How much free time do you have? Compared to the past, do you spend more or fewer hours on leisure activities?

I’m very busy on the weekdays because of work.
But I try to spend as much time as possible with my family on the weekends.
I go to Olympic park with my family about once a month.
We get in our car and drive to the park.
Once we arrive, we find some shade where we spread our mat and then we unpack our lunch.
Of course, the children are too excited, so all they do is run around the field. It’s pleasing to see my children running in the field in the nature.
However, nowadays I’m too tired from work, so I spend more time at home instead of going to the parks. But I cook at home to spend quality time with my family.

I don't have any corrections for this writing - excellent job!!  Keep up the good work :)
