B2 or C ward for foreigner @kkh

I am a foreigner and would be delivering in KKH . I want to save money as we are bearing all costs without any subsidy. So was looking for some helpful input as I should go for B2 or C ward. Till now pregnancy is completely normal but don't know what happens ahead. I am fine with sharing a room and any doctor for delivery.What all items I need to carry for B2 or C ward .
