I believe it is open as from 10 days ago. It’s bookable . Seems to be in close proximity to terminal 3. I’m interested to know if it’s accessible from the passenger walkway that leads to the resort hotels in the same area. The website says take a taxi ( all of 600 metres), but the drama involved in doing that would be too much.
It looks nice, isn’t outrageously expensive and I’d try it for connecting onto QR flights , so long as it’s easy to reach.
