I'm assuming from your avatar that you stay at the Polynesian sometimes? I discovered while there last time that they have a self serve Dole Whip machine in Captain Cooks! So it makes it easy to get one. I don't know if it's as good as the ones in the park, but it's the one that I tried.
Yes we LOVE the Poly and but are facing the reality that we may not be able to stay there in January!!!
And yes, I did notice the Dole Whip machine, but always walked past it. Pretty cool how they have it right there.
