Convenient for JHU students and families. If you have a student checking in, that is not 21, be sure to contact the hotel and get the name and title of the person that says that is o.k. for a 19 or 20 y.o. to check-in. We confirmed prior to booking, but our 19 y.o., at 1:00 a.m., was refused at check-in. Eventually, it was remedied, but not without a lot of effort.
