Hi -- people have written about the advisability of using Marhaba welcome services at DXB to speed through long immigration lines. When I went to their website, there were two levels of service: standard (90 AED, about $25) and diamond (150 AED, about $42), and only the diamond level mentions that they'll take me through 'expedited lines at immigration.' I think I saw somewhere on this forum that the standard level, too, got you through the lines quickly. Can anyone help with first-hand experience here? Do I need to spring for the more expensive service? I'm arriving at 11:30 p.m., so I think there'll be a lot of other flights coming in, and I'll be tired and wanting to get to my hotel quickly. . . . . . Thanks.
