Carnival seems to have backed away from the old days of having the deck servers pushing drinks. It really is going to depend on when you go, and what itinerary you choose concerning the party atmosphere. Seven day cruises are less likely to have that type of atmosphere.
I also noticed they didn't have a sail away type party when leaving the ports. I was disappointed about that. I always enjoy the band playing while we leave the ports.
This was the October 28th. 2007 sailing. Maybe they were between bands or something. I liked the decor though, and the enchanted forest was a hoot! I would not hesitate to sail on the Legend again.
