They used to also have a real yummy frozen orange juice and soft serve combo at the snack bar just to right of the Tiki Room. The orange juice was frozen to a soft serve type consistency and swirled with vanilla soft serve. It was called a Citrus Swirl.
I say used to have because that's what it used to be. They kept the name, but replaced it with vanilla soft serve swirled with orange flavored soft swirl (sort of like soft serve orange sherbit). It is good (well, it's OK), but nowhere near as good as the old Citrus Swirl.
I've never had a Dole Whip because I am allergic to pineapple, but in many years of watching my MIL eat them, I think they are different now than they used to be . Now they are a pineapple flavored soft serve ice cream. I think they used to be more like the old Citrus Swirl. (I'm sure someone will post to confirm or deny).
