I am new to the town and also struggling with the similar issue.
Klay, Little Elly and Little Millennium are the biggest preschool chain here.
1. Mostly these schools have a van service themselves.
2. Go and visit the schools. When I visited the Little Elly that is located near to my home, I found it in a bad shape. No infra, smells everywhere and No safety measurement. It was kind of stinking. They were hardly speaking in English. But, Little Millennium is the opposite. I found it better than the Elly. But, the fee was almost same in both the preschools.
3. This was the case in my area. It could be the opposite for yours.
Do visit the schools and decide.
I do not know how it will affect the school admissions since I am also new here.
