Absolutely! The Couples Session package is specifically designed to accommodate two people being photographed at the same time! The reason why other packages cannot work is because it's considerably more time intensive to shoot two people, as both subjects always require outfit preparation, posing and professional coaching. Couples shoots also require significantly more time for image re-touching, as now the retouching process applies to twice as many subjects in the photo.
Note: If your intention is to shoot together in order to keep each other company we can definitely organize back to back sessions that will let your friend keep you company during your shoot, and vise versa.
