I just come back from Dubai last weekend. The procedure is easy, if you have RP in Qatar, you can travel to any GCC countries on arrival visa, only need to pay 100 dirhams for Dubai and you need to fill some form before que in Immigration line. And the information I got from Emirates airlines, if you (in this case myself as holder of spouses visa/RP Qatar) travel alone I have to get the visa organized by them and cost me 300 riyals. This I think depending on your job title also. You might can get in without pay. But if I travel with my husband as my sponsor I only pay 100 dirhams on arrival visa just like above explanation. Where are you heading about?
