Total charge is about rm2700++. I managed to get a single room as Dr Thow seems know there is a empty single room and assisted me somehow. Therefore I can overnight there.
As for the payment procedures , I waited for two FPP and overall took me about 30-45min as the cashier needs to go to verify etc
For the checkup is about RM 125 per time. All the payment can be using credit card.

Mine also first child. But I will recommend you to book early. They are using whatapps for the booking. Quite convenient. During my wife check up in March. Dr thow seems fully booked until July or August. There is a signboard indicated there.
