I tried it today at the Epcot F&G Festival and my opinion is
I had hoped they would do something such as add the rum into the mix and get a combined flavor. Apparently what they did was run the Dole Whip into a glass and then add the rum over the top, so that it pooled near the bottom.
It really did not enhance any of the flavor. And when I tried stirring near the end it was just yucky.
It was definitely not worth the $6.25 that was charged.
