Private hospital or private KKH

Choosing the right Gynae I would like to know how much does it cost for a private Gynae? Should we choose private at KKH or Private Gynae? My husband and I are new to this and we would like to be able to consult the same doctor throughout our pregnancy but was told it could cost us up to 20k. Has anyone seen Dr Suzanna from KKH? Please share with me you experiences and would appreciate if you could give us a breakdown of it :)
