1. That is correct, the Park no longer has black rhinoceros. The last pair was moved to the Honolulu Zoo in Hawaii once they could no longer be maintained in the mixed-species field exhibit.
2. For the safaris, it is going to depend on what experience you want. All of the African field exhibits are viewable from the Africa Tram, while the Asian field exhibits are only visible via the paid safaris. The caravan safaris will take you directly into the field exhibits for an up-close safari experience; however, there is no guarantee which exhibits you will enter — it could be one of the African exhibits or it could be the Asian exhibits. The cart safaris take you around the tram path and the old monorail path, depending on if you pick Africa or Asia. “Rare hoofstock” is hard at the Safari Park because many of the species are rare. It’s going to depend on whether you want an up-close experience or want to see everything the Park has to offer.
