Got the official email just now, so no overnight visit 
"Our Open Houses and Admitted Student Programs will shift to an online format that will run throughout the spring. We are working to create visit options that will reduce the size of groups for information sessions and tours. Updates to our offerings will be shared on our website.
While we are not able to host students in our residence halls, we are working to develop a number of online opportunities for you to connect with our students, attend webinars with faculty and staff, and continue to learn about Case Western Reserve University. An ongoing virtual open house will run throughout the spring, and you’ll be able to choose from multiple events."
