The window seats at O'Hanas are spectacular. Many of the windows look towards the Seven Seas Lagoon and the Castle. When I ate at O'Hanas in September, I did not have a window seat. I could, however, still see the Castle and the electric water parade. It was really neat.
O'Hanas has a terrific dining room and I really like the atmosphere of the whole place. Curiously, the Unofficial Guide gives it a low rating for ambiance. I really don't understand how they can justify that.
