Official closing of Future World is generally 7 pm, but I have heard that some attractions stay open. I think this includes TT, MS, Spaceship and Honey. Did I miss anything? What about stores and restaurants?
Garden Grill is open, but NOT the Land's food court. Garden Grill often does not take walk-up's after 7:00, so if you don't have a PS, don't bother to walk all the way to the Land. You might starve.
