Coke products, juice, milk, tea, lemonade (afternoons) and coffee are available throughout the day. The passion fruit/guava juice is also available in the lounge.
Wine and beer, along with Ku'ulei's Punch (which is actually a wine punch not rum), are served from 5-7. Wine and beer are available upon request during the dessert/cordial service as well, but only if leftover from evening service. Sometimes it is all gone. . .

The punch is also put out during dessert/cordials IF there is any left from evening service.
When we were there, cordials were minimal compared to years past. Amarula was offered as was Kahlua and Courvoisier--I think maybe one other--but not sure. Cream was offered to mix.
Hope that helps you!
