Give myself a travel trip [1]

I was am [2] very excited today beacuse because I made a plan for travel,. I will go to Hainan Island at next Friday. [3] Hainan Island is located at the south end of China,. From my city to there the distance is about 3,020 km [4]. I think it must be will be interesting that from the to leave a place of snow world and fly to a tropical rainforest. I've never been there , and so far this [5] is the most far distant place in my tour [6] stop. Besides, I felt feel it will be a big challenge for me since I will take my daughter by myself to finish this trip, but I love to accept kinds of challenges. I hope it is a good beginning for my new life , and then I 'll to achieve my plans step by step.

[1] The word 'travel' is usually a verb.  While it can be a noun, it is used differently.  A simple noun to use is 'trip'.

[2] Even if you booked the trip earlier today, you are still excited.  Therefore, you need to use the present tense.  If you use the past tense, it suggests that you were happy before, but then something happened and now you are unhappy.

[3] Add one space (' ') after every comma (',') and full stop ('.').  However there is no space before a comma or full stop.

[4] A native speaker would write this sentence differently:

"The island is about 3,020 km from my city."

[5] The reader does not know where you mean by 'this'.  Do you mean where you are now, or the Hainan Island?

[6] Your wording means that you are already traveling, and that Hainan Island is an additional location.  If that is not your meaning, you can write the following:

"I have never been there, and it will be the most distant place I have travelled."

I hope you and your daughter enjoy the trip.  Have fun!
