Booking Engine Bookable by Unit Type (grouped by Rate Plan)

Select the Booking Engine tab.

Select the Units and Unit Types button.

Under Search and Book by, select Unit Type (grouped by Rate Plan).

This will display a list of all your Unit Types, along with the Bookable Units available within each Unit Type.

Select a Unit Type to open a window where you can edit its name and description. You can also choose which individual units within that Unit Type will be available for booking.

Toward the bottom, locate the Units Remaining Threshold setting. This determines when a message appears on the Booking Engine indicating how many units of that type remain available.

Once you've made your changes, select Save in the upper-right corner. 

Navigate to Configuration > Rate Plans (Unit Types)

Find the appropriate Rate Plan and select Edit "rate plan" Settings

Select Images and Upload Images from your computer. Once added, select an image and Add Selected to your Rate Plan .

Repeat this process for any additional Rate Plans, and be sure to Save your changes.

Now your booking engine is going to display by Unit Types, and not individual units.
