^^^ LOL.. Westerners are going to find this creepy as hell. Even if the couple is in a serious relationship for many years, they won't be allowed to stay in the same room. In the West (and now increasingly in Asia), it is very common for individuals to stay together without marrying. But doing so in Qatar will result in prison time. This edition of the world cup is going to be a disaster for the football fans. Hundreds of thousands of fans will be visiting and in all probability, thousands (if not tens of thousands) are going to land on the wrong side of the law.
Honestly? Arabs find it weird as well and they are just used to it and there is this "if I lived like this for all my life, let the younger generation live like that as well!!!!" mindset going around as well.
I worked in hotels for most of my life and I can tell you that Arabic people who are out of their nations live like however they want without a problem at all, they never try to impose their cultural stuff into your western nation, well maybe when they grow to be a big number that live there, but not as a tourist because tourists wants to do whatever they can. But when you go there, it is like that for you because that's how they keep the power. It's a disgusting political situation that could probably never be changed.
