One possible version:
I’m very happy that the summer holidays are coming soon. I stall have enough time to do many things of my own. First, I am going to spend a week in the countryside with my grandparents. I really miss them . Then I’ll travel to Guilin with my parents. I’m sure we’ll have a great time! After that , I’ll come back and finish my holiday homework. I’ll also going to take some extra lessons to improve my studies. Besides, I’ll take enough exercise every day to keep healthy. How about your vacation plan?
Please write back soon.
Yours,
Jill
