I am a beaches brides and have contacted my WC about this and Yes you can have a photographer if they are staying BUT they can not be a professional with all of the equipment etc. So Beaches/Sandals saying yes you can but you really can not. Hand held camera, no extra equipment, no nothing.. that is not allowed. So its riduclous basically.
I have hired someone on T&C to take us off property before the ceremony to take our pictures!
