Yes, NCL had the gondola for $49 until about a week ago. I used the shore excursion credit to get a ticket for free. Probably why they raised the price as people could get them for free.
In early September the salmon are running so it’s a good time for bear watching if that interests you. There are trips to Neets Bay, Anan and other bear viewing areas out of Ketchikan.
I stayed in an inside on the Jewel a few years ago from Vancouver to Seward. I did not feel it took away from the experience at all. I spent most of my time at the Great Outdoors at the rear of ship with good views and easy access to alcohol and food. For Glacier Bay I was out on the bow. As a solo I just don’t spend enough time out on the balcony to justify the cost increase.
