If your intention is to know about how an Islamic country would treat a couple behave in a hotel/at the entrance of a hotel (not in your room). I would say, none is here to bother about you and everyone has their own work. Apart there are some com knowledge of behaving such as keep a little distance between you and your fiancee, dress decently as well as do talk to the officers and people respectly and in the way they should understand you both are a couple by law. All people in the world will understand the matter in the way in which we explain/show them the matter. I hope you understood!!! Good luck for both of you...
