Where to place "all" and "soon" in this sentence?

Some people are being held hostage. One of the hostages say:

1. Let's hope all this will soon be over so we can get home to our families.

2. Let's hope this will all be over soon so we can get home to our families.

3. Let's hope all this will be over soon so we can get home to our families.

4. Let's hope all this soon will be over so we can get home to our families.

I'm not sure about where to place "all" and "soon" in this sentence. What would be the more natural way to say the sentence? Thank you.
