I've been to Dubai Airport many times.

It's big.  Can get your step count up by walking from one end to the other.

Lots of fancy Duty Free shopping outlets in the middle, if that's your thing.

Usually lots of expensive cars on display near the duty free shops too.

There's a few hotels inside, if you wanna get some sleep.

Lots of food.

A couple of bars, with very expensive drinks.

And man, does the air conditioner work overtime.

I've usually arrived there in the early hours of the morning, and it's still around 35 degrees outside and you can feel the heat coming through the windows if you stand close to them.

But yeah, it's a pretty good airport - definitely worth experiencing at least once in your life.

Doha is pretty good now, too.
