We were on that cruise with a group of 30 people for a wedding and we had a blast. The events and parties at night were great and we had a choice on what to do from dancing to drinking and chatting on one of the top decks.
The ship is pretty old so it's definitely not the best in class but it was clean and well-maintained. The rooms were smaller than I expected (interior room) so for 3 people, it was a bit crowded. We didn't spend much time at all in the cabin so that was not really an issue.
