Emiratis tend to keep to themselves, away from the main tourist drag, so its highly unlikely youll get chatting on the beach indeed, most tourists only encounter one Emirati on their holidays: when they get their passport stamped at the airport.
Border control is staffed almost entirely by Emiratis (indeed, most bureaucratic roles are reserved for nationals), but this isnt the ideal place to strike up a conversation about local life. If you do have burning questions, keep them for a visit to the Sheikh Mohammed Museum of Cultural Understanding a brilliant initiative that connects holidaymakers with Emirati people for cooking lessons, traditional dinners and heritage tours.
Emirati nationals are far outnumbered by expats in Dubai, to the tune of almost six to one. The majority of the population is Indian, Bangladeshi, Pakistani, Asian and Western.
