一般來說,simple future tense 是(根據已有的資料而)作出對未來的預計:
例句:
The weather tomorrow will be warm and sunny.
They will come tomorrow. 他們明天會來。
而 present continuous tense 是指未來已計劃或安排了的事:
例句:
I am seeing my dentist on Wednesday.
Polly is coming for dinner tomorrow.
所以,一般而言 present continuous tense 會比較肯定,而 simple future 就只是一個預計/估計。
所以,用哪一個式要視乎要表達的意思:
I am having a trip to Japan next month. (隱藏的意思:這旅程已經安排好了,或者你已經很確定會去,等等)
I will have a trip to Japan next month.(隱藏的意思:你只是估計你會去,或者這旅程可能還是計劃中,等等)

You use 「will」or 「shall」 when making predictions about the future.
You can also talk about people's plans or arrangements for the future using the present continuous tense.
