We were there a month ago, the body lotion is the only product they still have in individual small bottles.
Shampoo/conditioner/bodywash all switched to large bottles w/ pumps, they are in the shower and at the bathtub. The brand they are using now is called Maile, it's a local Hawaiian organic product. I liked H2O but Maile is even better, glad they are using them now. I hope they will keep it at Aulani even when Disney eventually switches back to their own "H2O" products.
