Virtual tours don't have to be "too complex." Often viewers have a difficult time following through multiple rooms.
A simple virtual tour can include highlighted rooms, areas of great interest, or a walk through of the main home features. Regular still photo galleries can supplement the virtual tour, filling in the blanks of smaller rooms, laundry areas, etc.
