Dubai is generally too hot for Westerners in the summer, but is definitely worth visiting in the winter when it is cooler. The culture is amazing in the city and must be explored via the markets, shops and historical buildings in the centre. You can even hire a boat and sail for a while around the marina. Dubai caters for the tourist trade and looks after its guests well, as is demonstrated by the hospitality. The Ascot Hotel is one of the best in the world for customer service.
