She is definitely on the older side, and its pretty evident, but the Independence can still hold its own. There is plenty to do, from the classic flow rider (I got up this time, granted for all of 10 seconds), water slides, promenade, and more. I think it has another 10 years, MAX, of being relevant before it slips away into irrelevancy, especially at a lower price point than its newer counterparts.
With all that said, would I recommend going on this ship? Definitely not if its your first cruise. There are so many more newer and better ships out there and you’d definitely come out of the experience a little put off by the tackiness of this ship. But again, Independence does quick, cheap routes, and for that, it does the job.
