I just came across a new resort the Semara that is opening up that has a kids club and is in Seminyak between La Lucciola and the new W hotel. This could be the answer to some parents prayers (mine at least). I love staying in this area but up until now it has not had anything for kids. It looks great.

No more taxis from the Dynasty to Seminyak nearly every day or night.
