Preference groups (or types) are used to categorized the various preferences saved to a profile. OPERA Cloud is pre-configured with preferences for room features, smoking, floor, specials, and (room) Key Options.
You can create additional preference groups (for example, pillow, music, newspaper) as well as the preferences associated with these preference groups.
It is also possible to define the number (quantity) of preferences that can be selected for a particular preference group. For example, only one smoking preference (either smoking or non-smoking) is logical but several newspaper preferences could be selected.
