I am not positive, but about 99% sure, that the official Disney dining sites have stated "Dining Plans Not Accepted" for any location that does not qualify as a Quick-Service or Table-Service credit for months. This should not be taken as an indication that these locations will not accept snack credits!!! If the dining plan changes materialize today as expected, I have no idea if they would let you use a Quick-Service credit to get 3 Dole Whips at Aloha Isle, but I sincerely doubt there would be any problem with using snack credits the same way as before.
