However, in Dubai, there is (or was) and unwritten rule that says you can take one guest in per F passenger. I don't think you can pay for access to the F lounge directly at DXB, only the J lounge.
being in F allows you to guest regardless of status. You may have to pay for one child or they may (more likely in oz) let you guest all 3.
