I haven't been on one, but we visit the islands frequently and I pass the ships on my way out to scuba. They are very small compared with the Magic and Wonder and the majority of the people we see coming ashore are seniors. I do have a friend that went on the NCL and complained about a lack of activities on the sea days to and from the Midway Islands, but said the excursions were great. It may be a good way to see the islands if you've never been. Go in the winter so you see the whales.
