Last January, visited Dubai for 2 weeks. At that time the weather was good, quite cool but windy. Most of the places I visited was all built up, clean. Did a trip to Abu Dhabi by bus - comfortable and good. Did a desert safari, just for the heck of it - nothing to complain about and all was meticulously planned and arranged.
Yes, I would go on a longer visit again.
Very rarely would you see or meet a local - mostly foreigners.
The most unusual observation I made was, seeing the most number of Bentley, Lamborghini, Maserati, Porche, Rolls-Royce, Aston Martin, Ferrari etc., all in one place, in a big car park of a rental company - all available for rent!
Nothing comes cheap there!
