Some movie theater's have free summer kids shows, usually movies from the previous year. Depending on the showtimes, you could eat breakfast and then see the early show which has the lowest attendance. For example the theater I work at has free kid shows on wed and thur. Showtimes are 9:00, 11:30, and 1:45. The 1:45 is the busiest due to the heat and the 9:00 is the slowest because people are still sleeping.
