Hello Angela. Thanks for your question. The
Disney Dining Quick Service Plan is not available at Splitsville - currently they only accept the Disney Dining Plans offering Table Service credits. I've included a link of all locations accepting the 2013 Quick Service Dining Plan above. If you're looking for Mac & Cheese on the Quick Service Dining Plan I highly recommend
Wolfgang Puck Express in Downtown Disney Marketplace. It is one of my very favourite quick service locations, and their Mac & Cheese is fabulous - actually all of their food is delicious and my mouth is watering just thinking about it! The food at Boma is also delicious, but I'm not aware of any quick service locations offering their specific soups. You could check with The Mara at Disney's Animal Kingdom Lodge, a quick service location that has daily soup offerings that may be similar to what you are craving. There is no way to know ahead of time what they will be, unfortunately.
All of the menus at the Quick Service dining locations are available on the
Walt Disney World website - you may want to peruse them ahead of your vacation to get an idea of the locations you would like to eat at. Please let me know if I can assist you any further. Thanks for visiting the Disney Parks Moms Panel, I wish you a magical day!
