If not, then you should so that you can get the answer from them directly as to why they came up with this rate now. I too, had some kids, and 2 were already graduated from high school in this school, and the rate was never our problem (maybe only the recent driver they had which was a not Filipino). I would prefer to pay in this rate per child as the school time in the morning requires them to be picked-up early say around 6am and we had some work also. I don't think you can find this same transport fee if you'll take a private taxi from & to school vice versa.
