Hi Candyce,
Thank you for reaching out and sharing your requirements regarding booking event spaces and conference rooms by the hour.
Currently, OS Property together with OS Calendar is primarily designed for booking properties by night or for specific time periods. OS Calendar is an add-on for OS Property, and unfortunately, it does not support hourly booking within the day as you described.
For your needs, we recommend considering OS Services Booking. This system is specifically built to allow customers to book services and spaces by the hour, making it ideal for event spaces and conference rooms. You can view a demo here:

Additionally, OS Services Booking allows you to configure payment options, including disabling online payments so you can process them offline as preferred.
If you need further information or assistance with setting up the system, please feel free to contact us.
Thanks
Dam
