CCI also has a free continental breakfast (pretty good variety and filling), which really helps with the budget over a multi-day trip. I don't think HoJo offers breakfast, but there are lots of places for quick meals on the way to the parks, e.g. McDonald's, Starbucks (in DTD and in the parks), Panera, etc.
Yep, the breakfast at CCI is pretty good for a continental breakfast, definitely helps a family on a budget. Another think to consider OP is to ask for gift cards for gifts to places nearby/in park like McDs and others theluckyrabbit mentions to help. And also turn in your change to coinstar for a no service fee gift card to Starbucks, Mc Donalds, etc. i've also done online surveys for gift cards. A $5 gift card here and there saved up over the course of the time you have can really soften the blow come time for your trip and make it less stressful.
