I don't believe BWV has a zero entry area from what I recall. It's being refurbed right now though (Luna Pool) - maybe they will add one! (unlikely I know)!
No BWV does not have a zero entry pool. It's not that big a deal in my opinion. My nephew had no problem a BWV when he was 2 they have a big set of steps in the shallow end and its not like you would leave them alone at that age. They also have a kid area that he loved.
