Yes it is. My fiance and I were just there on March 6th!! Tickets are purchased online for entrance and you can choose what time you'd like you go in (if tickets for that time are available). Masks are mandatory. They take your temp upon entrance (using a machine that reads your wrist). Only small amounts of people are allowed in to see Ghosts of the Library and Through Lincoln's Eyes and everyone stays very spaced out. I hope this helps!!
Yes but you have to wear masks and temp checks.
