Norwegian Spirit?

I have had alot of complaints about NCL. Not about Freestyle dining but about the lack there of activities and deck events. I had a large group sail on the NCL Sun (20s-40yr olds) and all they were disappointed. I think it is geared more towards the older crowd. They said that the whole ship was basically a ghost town by 10pm and there were no 24 hour food venues or midnight buffets. They were all kinda bummed about cruising b/c this was their 1st cruise. Then some of them went on Carnival and said it was way different than NCL. They got bored on NCL but had a blast on Carnival. Some of NCL's newer ships look really nice though and I feel that cruisers would have a different view on them. They seem to offer more. This is just the replys that I have gotten from former clients of mine. I however, have not sailed this ship. I always sail Carnival.
