Say 1 first day (evening) and 2 the second (morning & night)? How do you request properly to not get overcharged?
The system is set up for users to select the calendar date and number of walks per day. So, in this case. I'd likely select just the second day from the calendar (as that's when the majority of walks are scheduled) and choose 3 (for the total number) walks. Then, I'd suggest documenting the actual dates and times in the message box when you send the quote. That way there's written details that all agree to and it ensures Rover support for the entire coverage time.
