My wife and I just returned from an overnight stay at Star Island. As mentioned by other reviewers the Oceanic is a 19th century hotel and it is not a luxurious place to stay - but the place is amazing. There are many places to quietly reflect and recharge. My wife said it best, as you stay out there the rest of the world just melts away.
I just caution people to understand that this is primarily a retreat, meditation and (self-help) conference center. Meals are hearty but there is no choice. Also, you are paranoid about your possessions there are no locks on most rooms.
This might sound negative but the overall experience is still very special and profound.
