For our Disney(land) trip, we stayed at a motel ~ 1.5 miles from the park (Canadian walking distance) and the thing my kids LOVED was we walked by a 7-11 every day and I would buy them a slurpee on the morning walk to the gates. Probably $20 for the week (and likely not much worse for you than a typical vacation breakfast).

The "make your own waffle" station at the included breakfast was also a huge hit. The park and rides were satisfactory.
