Reply To: Fixed reservation time

I tried a lot of combinations and i always have some error message like “The departure date has to be after the arrival date” and others.
Can you post the full code please? This part is a little bit confusing for me.

I want to put:
From “Today” at 13:00
To: “Today” at 15:00 (this part hidden)
Always “To” 2 hours later.
