Line up, and the person behind the desk will fix you up with 3 vouchers. 1 for free VISA, 1 for free breakfast and 1 for free hotel (Oryx Rotana if in Biz). Then you walk through the security screening and head towards immigration, where you give your voucher(s) and passport. After you're through, and at the exit area you will find some people with folders "collecting" people being transported to the different hotels. Find the person responsible for Oryx Rotana (or whatever hotel you're staying at), sit back and wait for your shuttle.

They don't really check your voucher when entering the shuttle, so I guess in theory someone could sneak on the shuttle.
