You tell them what night and which showing - early or late.
The tickets are sent to your cabin. When we were on CP
there were two different current movies two nights each that

less popular movies that you just showed up for. One of
the movies requiring reservations was Calendar Girls, whileone of the movies that did not require reservations was
A Hard Day's Night with the Beatles.
