"Check out" date error?

Hi,

I have noticed that when there is a booking, for example from july 3 to july 4, the system shows:
Check in: July 3
Check out: July 4

But THIS IS A MISTAKE.
The client stays 2 nights, July 3 and 4, and the CHECK OUT DAY IS: July 5

I know there is an option for “Morning Check Out”, but this is very confusing for most clientes, as they are used to set on the hotel calendars only the “days” they stay, like 3 and 4, not the day they leave.

Several clients talked to me about this misunderstanding and we have to explain them this issue.

Is there a way to change the code to add 1 day to the check out date?

Thanks and regards,
Gabriel
