Not the world's biggest news but wanted to make anyone aware who might be planning on doing this on an upcoming trip. Loose ice and dry ice will not be permitted into the parks beginning May 1. You can apparently still go by Food and Beverage and gets complimentary cups of ice if you want to go that route. Disney is recommending re-usable ice packs instead. If you are staying in a room without freezing privileges then you may need to get fairly creative.
