I don't know. We saw people with soft serve ice cream cones, but I think they were near the main food places. The funnel cakes were in the "snack shack". We took the advice of some on Cruise Critic and got the chicken sandwich and mozzarella sticks to make a chicken parm sandwich. It was really good!
We were kind bummed we didn't have time to find the soft serve machine because we saw people with chocolate/vanilla swirl. On the ship all we could find was chocolate/strawberry or vanilla/strawberry. We didn't understand why strawberry was in every machine.
We had a great cruise and loved CocoCay.
