Had a great afternoon out Quad Biking in the Sinai Desert, March 2007. In total the trip takes in about four hours, around two hours on the bikes plus a couple of refreshment stops at remote bedouin camps. The scenery is fantastic especially when the colours change as the sun-sets.
My wife & I paid £20 per person which I thought was excellent value (even though my wife wanted to ride on the same quad as me). We paid the same as others who had a quad each, the price also included hotel pickup/drop off
I have no doubt this excusion is readily available from all hotels & businesses in & around Sharm, the activity will be the same but prices may vary.
Although the excusion is very cheap keep an eye on other elements, £5 for a photo, £15/20 for a DVD, £3 for a bottle of beer.
Don't forget you get very dusty . . .older clothes req'd, sunglasses & a local style headscarf from the local supermarket for £1.50.
I have posted a couple of photo's & a short video from my excursion, hope you like them
