day out, go to the Four Seasons. I am not sure what the price is, but I do believe you can get a day membership which allowes you use of the Spa facilities, beach and pool - its really lovely.

They also serve afternoon tea, which is delectable.

Souq Waqif, Malls, hiring a car and taking a drive around Qatar - keep to the paved road and you cannot get lost, all roads lead back to Doha eventually:-)

Hopefully your friend can get a day off at some stage, then head down to Sealine Beach Resort for the day. They have camels and horses there too, but usually just rides.

Hope this helps:-)
