First they’ll ask for your passport, second your marriage certificate. They take photocopies to register with the police station. No marriage certificate, no room!
Europeans they don’t ask for the marriage certificate so not an issue.
I have to book two rooms ?
Or get married 😉
You can book - but you most likely ( 99 % likely ) will not be allowed to check in unless married or if traveling on non-Arab passports.
Heard that even booking two different rooms may pose some issues as if security cams shows either going into the other’s room it may be problematic too. A bit of camouflage by checking in separately at different times and pretending not to know each other may work, but that’d be quite a hassle and will dampen things during the holiday. I dunno really. Maybe you’d be better off in Europe or so.
You need non Arab passports to do this
