I haven't stayed in the sail, but I've been inside. We went for High Tea, and that was worth every penny. After having tea there, I would say it has to be worth it. The inside is wonderful, the setting is classy, and the place is immaculate. We had friends who stayed one night during the summer and raved about it- the butler, the robes, the service, everything. I'm hoping to stay there at least once when we move to Dubai.
