Hi LS

I would suggest this alternative for your first sentence:

I'm on holiday/vacation at the moment and will be returning on (date).

I saw your title for this post, I think it might help in some other ways:
<tomorrow/next week/next year......>
1.I will go to Taiwan tomorrow.
2.I am going to Taiwan tomorrow.
3.I am to go to Taiwan tomorrow.

1.the most slight degree: indicating sb. is willing to do sth. or the act in the future
2.the medium one: indicating something pretty approaching, someting must happen in the coming minutes.
3.the large one: indicating destiny, something must happen in the coming seconds

<compare>
I will go there (someday).
I am going there (now).
I am to go there (right now).

I will be 18. (wait and see, and then I'll do that in my room)
I'm going to be 18. (maybe the birthday is right tomorrow)
