Actually the Presidential suite is the most expensive but is usually given to companies who hold conventions there, or famous people, and it is usually not charged.
Three years ago, a few of us from this board had a tour of the Suites at the Dolphin, including the Presidential suite. Michael Jackson had just been there before our visit, as had President Clinton and his family a bit before that. The view from the balcony is to die for, and the bathroom is the size of a regular hotel room. It is two stories high and just splendid. We heard the tossing ice off the balcony by Michael during our tour three years ago.
I love two bedrrom executives at either hotel...for a family of 5 it is awesome, and we don't get in eachothers hair.
