I notice a lot of brochures, websites and books say attractions are open May to September, but in Seward when in September do they close. We are planning a Sept. trip. The thing I would like to do most is a glacier cruise. Seeing whales would be a dream. My husband is more into flight seeing. What time in Sept do most of these attractions close, and does anyone have any recommendations for the best in the area. We are not up for a whole day on a boat.
