Mediterranean Harbor is themed to a southern European harbor town, with pastel buildings, Venetian canals, and a stone fortress across the water. Mount Prometheus smokes in the background. The harbor itself is the stage for DisneySea’s big water shows, so most of the park’s evening crowd ends up here.
Hotel MiraCosta wraps around the whole thing. Those windows overlooking the water are hotel rooms, and yes, the people in them have the best seats for the night show.
