The are currently renovating the Dolphin just like they did the Swan.
Just as a bit of added info, the Swan rates to no ones surprise just went up a little in the last week in response to the new renovations that were made to the Swan, so I would think that the same would happen at the dolphin once those renovations are done.
However I wouldn't worry if anyone has made dolphin reservations already and the rate goes up. I was told today that even though the rate went up at the Swan the rate on my reservation will stay the same since it was made prior to the rate increase.
