A variable room (or Room Rate) lets you define variations of a room where each variation may have a different price, required deposit or conditions. To create a variable product select Variable Room on the Room Type option. You should see the Variable Room panel. Keep in mind that you need to have at least one room rate saved on your installation.
The settings available for each variation are the same of the standard room panel. To add a new variation, simply click on the Add Room Rate button and select the correct rate in the Room Rate dropdown.
