How is it visiting Alaska?

I'm going on an Alaskan cruise with my parents in the end of July. I'm 21 years old and have never been to Alaska. I've never left the Eastern U.S. (unless Ohio is in the Midwest because I've been to Cleveland). I'm wondering how it is visiting Alaska because I find myself not completely looking forward to this trip because I don't know what to expect. I'm a big history buff, I like different cuisines, and I also like rock music. Those are my interests. I'm not sure if there is any history in Alaska. I haven't researched anything about Alaskan history or Alaskan cuisine. Anyways can someone help me out. I'm going to give you guys my travel itinerary if that helps. Thanks.
