Dubai
If you have more than 24 hours, try the "sand surfing". You will need long pants, shorts don't work too well AND then you can go snow skiing. An in-door single run was just finished about a year ago.
Go to the Souks (markets). There are spice, perfume and gold souks all within walking distance from one another.
Great Duty-free shopping at the airport. If you win one of the cars (each ticket is about $100) they will deliver it anywhere in the world at no additional charge.
Lots to see and many fine places to eat and drink. Dubai is "wet".
