Just wanted to add, getting an e-gate for non-residents is not a problem. I didn't feel like using 5,000 miles so I spent the 200 AED for two years. Just got it less than two weeks ago, without any problems. Yes, I am from a visa-waiver country. And, the clerk did ask me if I had a UAE visa; after I said no, he thought about it for a moment and then proceeded with the application. Weird!
