Yes, Giuseppe Carlini aka Pepe is the actual CDV.
Unfortunately, I don't know about the actual chief of animation or sports, but in general they are pretty well confirmed GOs, since the team is kind of large and the village is open 12/12 months with lots of regular GMs in general.
Some GOs I know personally that are there this winter (according to the latest info):
Yaman (resp. sailing), Moez (reception), Picasso (land sports), Monia (fitness), Yoyo (tennis), Aymen (animation). They are all long standing and very experienced GOs who should guarantee for a good over all team.
PS: As a side note, tell your friend to bring Imodium. The so called 'djerbienne' is pretty frequent in Tunisia, especially if you drink ice cold drinks, have too much orange juice, eat too many raw vegetables and salads, etc.
