Hi Rhonda,
Thanks for writing. I'm a single mom too and am always looking for a bargain for my boys and me! There are no specific special offers or packages for a single parent, however, there are incredible specials available throughout the year. My favorite cost-saving way to visit Walt Disney World is during a free dining promotion, when Disney picks up the tab for meals! Currently, Disney is offering some great Spring time rates for trips through June.

Each is incredibly themed, with wonderful pools, arcade and food courts. In addition, they all have great entertainment options and all of the "traditional" Disney perks including access to free Disney transportation to and from the parks and Orlando International Airport, and Extra Magic Hours. Finally, to save on concessions in the parks, I bring in my own snacks and drinks, and limit my kids to one Disney gift card at the beginning of our trip for souvenirs. They get to buy whatever they want, so long as it doesn't exceed their card's limit.
I hope some of my suggestions help you and your daughter have a magical Disney vacation!
