Exciting Summer vacation!

My summer vacation is going to start from this comming coming Friday! ('coming' could also be omitted)

I'm very excited because I have a plan to go where I want to go.

At first First, I'm going to Everland which is a famous amusement park in Korea.

I really expect the Summer parade of Everland, it is called "Summer Splash", and we can enjoy splashing water! (Sorry, I do not understand this.)

Second, I will go to Seoul to meet my friend.

One of my university friends got married 1 months month ago, so she prepare is preparing to have a house warming party!

The most important point is that I can do all of these with my family, especially my son!

I hope that everyone can enjoy summer as you plan. 

(I am not sure what you are trying to say.  Maybe you want to say - I hope that everyone will enjoy their plans for the summer.)
