We've had some dynamic CDs. On our last cruise, Mike Whitte seemed to be everywhere, warming up the crowd, and even joined the Classic Rock tribute band on a few tracks! Dru Pavlov would host special activities, such as Seinfeld, Friends and Sports trivia, complete with fun re-enactments of classic scenes. Dynamic CDs also schedule extra live music, such as having the headline musical act perform a bonus show in a smaller venue, or have the featured singers of the production shows perform their own acts. We enjoy participating in activities such as trivia and live music, and really appreciated having these additional special activities to attend. There was always something going on that we wanted to do, and we would move from venue to venue throughout the evening.
On the other hand, we've been on cruises where their seemed to be nothing to do, lounges empty for long periods of time in the evening, activities felt "old" and lackluster. Boring and ineffective cruise directing, for sure.
