guys, it's a fake tennis court !!
They had a similar "commercial" activity with Tiger Woods playing Golf on this Heli-port.
The area you see in the background is not Dubai city, as Toronto mentioned above.
It's the huge Jumeirah-area with several 5* resorts and a water park and of course the only 7* hotel of the world, the Burj-al-arab hotel.
The background of "agassi2" is the Jumeirah Beach Hotel, in "agassi1" one can see the newly built Madinata Jumeirah and the Jumeirah Beach Club and a Waterpark.
Amazing: everything you see in "agassi1" was built in the last 3 years! :shock:
In 2001, I was lucky to spend 3 days in the hotel next to the BurJ Al Arab, the
Jumeirah Beach Hotel.

in 2001, only this hotel, the Burj-al-arab and the waterpark were built!
and we could visit this amazing 7*-hotel,
hotel with heli-port
bathroom in a standard room
main hall (inside of the "sail" shaped hotel)
in case you don't take a helicopter to fly in, they have a fleet of at least 5 white RollsRoyce to pick you up!....
and a very nice night combo
