If you are from another nation, you will get visa on arrival if you hold a professional title (Arabic wording of visa type, not the job you do).  Examples of professional title - Engineer, Manager, etc.  Housewives travelling alone may not get a visa on arrival, unless travelling with your spouse holding a professional visa.  If you do not satisfy these conditions, the airlines (Emirates, Flydubai) can help you obtain a visa when you book ticket with them.  Next option is to book your travel through a hotel or an agency who will get you a visa & hotel room.

If you travel with your husband and your husband has a professional like engineer, manager, doctor etc. you can get the visa on arrival!

secondly, it also depends on your nationality!
