Dude 6am viewing at Burj Khalifa sounds like THE thing to do, haha. I'm going to be in Dubai for the first time in a couple of months, and frankly I don't want to go. But I think I'll follow in your footsteps and do that 124th floor cup of joe at 6am. If I do, I'll cheers to you my friend :)
It is much better to go 6am than 6pm! Because after 7 or 8 am it gets very crowded. Some of my friends went yesterday at 4pm, but had to wait 2 hours in line!! No thank you I say!
