Based on your calendar wkend vs wkdays strategy needs adjustment.
You already sold nearly all High Days (Fri, Sat) to people staying for 2 nights only. This makes your job to sell Low Days (Sunday~Wednesday) far more difficult.
If 70% occupancy is your goal, sell rooms as if Tues, Wed are meant to be unsold but rest MUST be booked.
Demand for Sunday, Monday, Tuesday arrivals are far less than weekends. Unless there is big demand for business travelers in your market you want to avoid this.
Example of how to manage calendar in general. Set different strategies for High, Mid, Low seasons.
