YewChung ITLP program / Kingston Playgroup / Anfield Playgroup - any comments

May I know any advice and experience sharing for these classes :
(1) Yew Chung ITLP program

(2) Kingston playgroup

(3) Anfield (Kowloon Tong) playgroup

My girl is offered AM class in (1) and PM class in (2), both will start school in August 2010 when my BB is 1 yr 8 months old.

My husband prefer to enrol our daughter to a school with more exposure to native english speaking environment.
