A lot of people wonder if the photo caravan safari is worth the money. Well, it is! It is $140, but since I volunteer/work at a zoo I got it for $90! If you tell the person at the safari ticket both that you volunteer/work at another zoo they might give you it for $90! The tour is 2 hours which is a lot better/longer than the 30 min Journey Into Africa tour. My tour didn't even go into the South/Central African field exhibits (the ones that Journey Into Africa take you through). Also, it takes you though the 2 Asian field exhibits which you cannot see another way (except if you do a few other extra fee safaris). On my tour I saw a baby sitatuga, a baby Indian rhinoceros, and a baby giraffe. The best part of course is feeding the giraffes in the beginning of the tour! I hope this helps you decide to do it!
