Thanks everyone for your ideas! All are really helpful!

Jack - Yes, he is a Qatari national. I am thoroughly aware that it is a Muslim country and it will be my first time visiting. I'm excited (and a little nervous) to visit! I'm not an expert on Islam, but I know enough to know that allowing me to stay with them (and my fiancee) isn't exactly the norm. All the more reason for me to be thankful that they have allowed me to do so! I expect things to be different, but so what? I am only nervous because I don't want to accidentally offend anyone or embarrass my boyfriend and his family or myself. While he was studying in the US he learned about how Americans live; why wouldn't I want to do the same? He's proud of where he's from and I can't wait for him to share it with me.
