So in my car I have 3 different costumes just in case.
What really gets me is keeping my spiels straight bcecause I have end up saying "Welcome Ladies and Gentlemen to the Hollywood Tower Hotel where we turn the music industry up side down!" guest just look at me Im crazy! Which I'am a little when I do 4 different attractions in one day!
Examples of grouping:
Thunder Mountain, Splash Mountain, Space Mountain, Barnstormer
Tiki Room, Country Bears, Philharmagic, Presidents, Stitch, Monsters Inc, Carosel of Progress
Swiss Family, Character's House
Pirates, Its a Small World
Haunted Mansion, Buzz
etc, etc, etc
Definitely did not know they rotated parks as well as locations.
But this is not true with park operations which has more specific training and such.
