You are going to LOVE it. Alaska is amazing. Aside from the glaciers and the mountains, there's this really cool bookstore in Ketchikan...I haven’t done it but my Gf has, we chose Princess specifically because they offer land and sea packages and my GFs big regret from her previous cruise was she didn’t see enough of Alaska. We’re doing a 7 day cruise from Vancouver to Anchorage followed by 5 days in Princess lodges at Denali, Mt McKinley, and Fairbanks. It was nice to let someone else take care of the travel and lodging aspect and just pick which excursions we wanted to do.
She said we can do a more relaxing DCL cruise “next time”, which made me laugh because she already knows I’ll want to go back.
I will say, having done Alaska twice with DCL, I would like to try it with another line such as Princess. Because Love Boat was a thing when I was a teen.
