When I was preparing for our 2006 trip I read about the dole whip here on the disboards and knew I just had to try it...it was delicious.
I had another when I returned in december 2008 and it was just as good.
Next trip mum and I will be on the qsdp(as opposed to being on a very tight budget like in 2006) so we will be having a couple of dole whip floats to maximise snach credit value ;-)
