On the left side of the Aulani home page, where it says book rooms or packages, there is an excursions link. Click on that link then click on Reserve an excursion online. It shows a page that says you are leaving the Aulani.com. Click the Proceed button. The next page shows the excursions. Scroll to the bottom and there are links for all the
ABD excursions. If you click on each excursion you can see the details and the prices. There used to be more, now there are only 4 excursions listed. The surf school and snorkeling excursion aren't on the website any longer. When we were there last October, I just booked my own excursions. When I compared booking the snorkeling with ABD, for example, versus just booking the same tour with the same company there was a high premium for going with ABD and it wasn't worth it to me.
