Men could not have facial hair and sideburns could not extend below the earlobe . Hair could not touch you collar. Black shoes ONLY except the staff in cash control, they were allowed ONLY brown shoes. You would go to the time shack, locate your time card and punch in. From that point you had 20 minutes to change into your costume and report to your assigned work station. At the end of your shift, you had 20 minutes to go to wardrobe, collect a clean costume , return to the locker room, change and clock out.
The locker rooms, when I worked there were located behind the scenery for the Grand Canyon diorama that the train runs through. If I recall correctly, the Womens locker room was behind the pre-historic version and Mens was behind the present day representation. The employee parking lot was where California adventure now stands and the back lot where all the maintenance and construction was done is now toon town.
