Rokko Pass for Kids

Hi,

This is my plan and I have 2 adults and 3 children (age 8,10,11). I have Kansai-Hiroshima Area pass for all 5 of us. I will get Rokkosan Tourist pass (1000 yen) for 2 adults. Should I get Rokkosan Tourist Pass with 1000 yen for my kids as well or there is a better pass/option for that? After some calculation, the kid's fare worth 1130.

1. JR Train from Shin-Osaka to JR Rokkomachi
2. JR Rokkomachi - Bus 16 - Cable car - Bus to Rokkosan Pasture
3. Rokkosan Pasture - Rokko Cable Sanjo Station
4. Rokko Cable Sanjo Station - Rokko Garden Terrace
5. Rokko Garden Terrace - Rokko Cable Sanjo Station
6. Cable car - Bus 16 - JR Rokkomachi
7. JR Rokkomachi - Shin-Osaka

For Kids :
Bus 16(by Kobe bus) : Pay in cash 110Y(x3)/oneway
Cable and Sanjo bus : Buy "表六甲周遊乗車券/Omote-Rokkosan-shuuyuu-jyoushaken" 680Y at ROKKO CABLE SHITA stn.
