would recommend Madinat for that time of year as it is an arabian style palace with three hotels and plenty of entertainment, restaurants etc.
With two weeks I would also recommend a trip to Abu Dhabi where the Emirates Palace hotel is amazing...not a lot else around there but nice drives and we went out to a place called Liwa Oasis to see what the country was really like before construction !..quite spectacular.
Also driving north in to Oman is amazing so I would recommend a night in Musandam. If you are interested in diving or any such sports, a trip across to Muscat could also be in order.
In my experience there, there is no shortage of things to do, if you make a bit of an effort !
there are eastern european and many other nationalities of hookers if you look hard enough but they tend to target "high fliers" !!
