My rebel spies report that they are starting overnight rehearsals in the theater next week (if they haven't already--these Bothans are sometimes hard to pin down). Once they have all three cast groups trained, approved, and "put-in", they will create the final "grid" which is the recurring schedule. Typically a full-time performer would get four days (half-days on the eventual full schedule), a part-timer might get one or two days, and subs are pulled when needed. Some subs are approved for other shows at the resort. This applies to both the principals and the ensemble.
