What do you want in a pool?
The thing about HoJo isn't the *pool* (which is a lovely, basic, pool in the garden area), it's the entirely separate water-play area.
DLH's pool is 2 or 3 separate (or so it appeared to me) pools that are large-ish and freeform-ish, and there's the big slide(s).
Some people want the play areas with a pool. Others want to really *swim* in a pool. They'll probably think that different pools are the best! So to answer, beyond family friendly, what do you want in a pool/pool area?
