In the company I work for it is called an orientation trip. It is a global practice to provide such kind of trip to each employee and the spouse accepting a job overseas.
The hotel we stayed at was Hyatt Regency, a 5-star hotel located in Deira next to the vegetable and fish market. The hotel was great, well it should have been as one night stay was something around 1 thousand AED (~ 180 EUR or 270 USD).
