- You can set the "availability window" to "all dates not available".Then manually only open the weekends on the calender.
Or
- You can set check-in days to friday-saturday and check-out days to saturday-sunday and limit stays to max 2 nights.
BTW If not using "professional tools" only check-in day can be set, then be sure max stay is set also to 2 nights
