I don't know about the amusement park but the safari is 25 for adults and 22 or 20 for kids.
They have different plans monthl3
They probably have it on their website! That will have all the info
I am not too sure, but I recommend getting the Diamond Elite Passes which work for the entire year, and include really close parking, lunch, dinner and a snack, 2 line skips and free rides to all rides.
I don't know kids but adult is $43
