There is conflicting info because there are different ways to book club, on a regular "cash" stay, or through DVC booking, and the two are different.
For cash stays, the rooms are on the fourth floor (the lobby is on the third floor), and have guaranteed Arusha savannah views. Arusha is the best savannah at Jambo, and has lots of giraffes!
The Club Lounge is on the sixth floor, and that's the same floor where the DVC club rooms are. Those DVC rooms do not have arusha views. Instead, they either have (I think fairly poor) sunset savannah views or pool views. There aren't many DVC club rooms, so they're very hard to get.
We stayed club on a cash stay and we really loved it! We had a great room location on Zebra trail with a great view.
