<p>My kids both attended Jesuit colleges (different ones). Their dorms were either coed by room or by floor, depending on the configuration of the building. There were no visiting restrictions at either school. They each worked out any concerns with their roommates/suitemates. </p>
<p>I attended a Catholic university in the 70s. The school had only gone coed the year before I started. The dorms were all coed by floor and there were no curfews or restrictions on visiting back then.</p>
