Depends what you want. The suite concept at the Kea Lani is great for families. If its 2 couples going, then 1 will share a sofa-bed.
As for the view, everytime I go and opt for the garden view I kick myself for not getting the ocean...its incredible.
We have found the hotel great--service, separate kid and adult pools, good beach. As for weather the Wailea area is a sun belt compared to other areas of the island.
