Thanks ladies, you all brought up issues that I've been thinking about.

It's not a case of thinking the curriculum at CC won't be up to scratch, I know they all have to teach the same things, so that's all good. That's also why I'm still keen for him to stay at CC one day a week, he loves it!

It's a mixture of:
- The kinder being much closer to the school he'll be going to (hopefully making the transition easier)
- Increasing his days of activities to 3 (rather than the 2 he's doing now), again in preparation for school
- It works out to be cheaper to do kinder AND CC rather than just CC
- My job is very flexible - I set my own hours and work in the area we live in, so the drop offs/picks up will be ok, no different to when he's at school really
- Summer holidays I can pick up the days at CC, but the mid year breaks I can't. Again, not a major issue because of the flexibility I have with work. DH also has the ability to work from home if we get really desperate

I'm sure issues will arise - kids being sick etc, but that will happen whether at CC or Kinder...

I think I just made my decision! Thanks for helping me work through all the possible scenarios and issues, that's exactly what I needed!!
