First, we did enjoy our cruise. We like being at sea, the rocking motion and the noise of the waves at night.
Also we went with my wife's two sisters who were fun. We have done many cruises, somewhere in the teens and I am a Platinum member. I have done the Hawaii cruise 4 or 5 times now.
Pros: the gym was great for me. I found going at lunch time was best as there were few people there and I could get a pretty much uninterupted workout. The staff were especially pleasant and helpful. Embarkation took just a few minutes perhaps because we arrived latish, about 1 1/2 hours before sailing.
Cabin was smaller than most cruises I have been on but it was perfectly satisfactory. Service was good. We needed a foam topper to make the bed more to our liking. It was readily provided but I have never had to do that before.
