I have not done this cruise, but just got back from a week on the Big Island. Are you wanting to do a tour or rent a car out of Hilo? Hawai'i Volcanoes National Park is about 45 minutes away by car and it looks like several tours go there out of Hilo.
The Kīlauea Volcano is currently erupting (we had an amazing experience seeing it at night). No idea if it will still be erupting come February (it has been starting and stopping since Dec 23, 2024 most recently). If it is that would amazing to see but also brings more traffic. You can see a live stream here:

Closer to Hilo there are a few different waterfalls (Akaka falls, Rainbow falls, Boiling Pots) you can see easily and black sand beaches where you can see sea turtles. We enjoyed a visit to the Mokupāpapa Discovery Center in downtown Hilo (museum focused on the marine areas/life) and there is also the ʻImiloa Astronomy Center if you like museums.
Two places we wanted to go to but didn't make it to were the Waipi'o Valley Overlook (just over an hour north of Hilo with a view of the beautiful valley) and the Hawai‘i Tropical Botanical Garden (15 minutes north of Hilo where you can walk along lush vegetation).
Enjoy your cruise and time in Hawaii.
