Just got back last week from AKL and I used the shampoo/conditioner daily to wash my hair and DH washed his twice or three times, my hair is short, but thick.
First off the getting lather is very difficult with the water being soft or is it hard. Anyhow that is why no lather forms if you notice you don't get much lather from the soap either be it yours or theirs. I used only two bottles of mickey shampoo/conditioner in the 11 nights we were there and found it not necessary at all to have my own.
