Re: 2 questions 1 You could use 'will be staying' too. The present progressive is used to show a fixed arrangement.
2 I think that it sounds better with the verb 'be', instead of using the present, though with another verb, you could say 'is staying'.
3/5 Because it's 'probably', so it's not an arrangement.
4 It's an arrangement
6 I'd used 'going to' because we don't know for sure until the person answers whether it is definite. |
