Northwestern University in Evanston, Illinois–which is an upscale Chicago suburb located right on the shores of Lake Michigan. Easy to double major, but not so easy to be admitted as a theater major. Unfortunately Northwestern’s admit rate was 8.39% last cycle so you need to consider schools with higher rates of admission.
Kenyon College in Gambier, Ohio has an attractive theater & is a liberal arts school, but it is small & rural though charming. About 1800 students. The admission rate is above 25% to the best of my knowledge.
