You're correct that Columbia and Wharton don't really care about the visit. it's more for you--but don't be so sure that the visit will not change what you want to say in the essays. That would actually be the only reason to delay. Also, your chances in round 1 vs. round 2 are not dramatically different, so if you have visits planned, I would say wait until after your visit to submit.
