Is the theatre open to the public during the day?

Yes it is open to the public

The theater is only open to the public during showtimes the box office is open 7 days a week There's a gift shop For Hamilton across the street in the Paramount Hotel

Only the box office is open to the public. The gift shop for Hamilton merchandise is actually across the street. That is open during the day, and up until midnight I believe.

Just the box office

Don't believe so.

I believe that only the box office is open during the day. The interior is not, although they may have a gift shop for merchandise available.

Not that i know of
