Thanks a lot for your answers.
I am currently booked for two nights at the Mandarin Oriental before heading to the Rosewood for one night. I am not sure if the Mandarin is already too dated and I am also not so sure about the beach at the Mandarin. But I will see it for myself. As for the Capella, I cannot see myself staying there at the moment. The décor of the rooms and architecture of the buildings itself do not attract me.
