Let me start off by saying that the staff on board the ship was EXCELLENT! They were knowledgable, friendly and very helpful.
That said, there were inaccuracies in the listing that soured most of our experience. The pick-up time was off by an hour, which was very frustrating as we stood in the heat on the dock waiting and waiting. We also were not aware that we would need to spend $10 per person round trip each time we wanted to leave the boat. This added up! And although the room was basic and fine, it did not match the descriptions. The photos show towels on the bed, and what we found were just sheets. You had to go and request towels. The bathroom also had nothing in it - not even soap. All of this would have been fine if we'd known in advance that it was meant to be a rustic camp-like experience where you really need to bring everything with you. And if that is the case, the cost ought to reflect this.
They have a wonderful mission that you would only know if you asked -- they could do a better job making this clear in the listing. Hopefully they will work out the kinks for next year's season.
