There Are Particular Rules For Couples
There are specific regulations and social practices to be aware of if you're traveling to Qatar as a couple.
Until recently, it was illegal for unmarried couples to share a hotel room. At least for foreign tourists, this rule appears to have been loosened in recent years. It still applies to Qatari spouses and foreigners living in the nation, according to recent sources.
If you're concerned about this, stick to foreign hotel brands (for example, the InterContinental) or just email your hotel ahead of time to double-check their policy.
Although homosexuality is prohibited in Qatar, it is fairly uncommon for guys (such as business travelers) to share a hotel room.
