2xlek If you're here to explore Qatar, it certainly doesn't hurt to come down.
Try to squeeze a bit out of them, and see if you can negotiate in your package to use the hotel's gym and internet...

That leaves you with $900 to go out and spend on explorations. But don't expect to have too many nights out in clubs and bars, because $900 evaporate quickly there!

And you can also get your sister to buy the car and you drive it for her :)

Let us know the verdict...
