Sign ups for Eleanor Roosevelt open houses are now open!:
A bit about ElRo tours. They're not really tours. Yes you sign up, and sign in when you get there, and hear from the principal in their auditorium, but then you're in your own to walk around the school.
Students are in different classrooms to talk to kids and parents. I didn't see any teachers when I visited. This year they're offering only 3 dates, which is new - and all have 3 time slots, also new. From personal experience, by the third tour of the evening everyone manning the school was pretty zonked.
My advice - take the subway so you'll get a real sense of the commute.
