Road trip from Dubai to Oman and back

Dear All

Me and my mate are taking a road trip , next week, from Dubai to Oman (Muscat ) and back.

Does anyone know which road signs to take lol? I've searched google and every other search engine possible for some sort of a road map and can't seem to find anything.

Also, obviously apart from our passport and DL, is there any other docs which we will need to cross the boader.

Any feedback would be much appreciated, including ideas on what to see and do.

Cheers - Rashida
