A topped out hourly CM with overtime will easily earn more than a newly hired Guest Service Manager for the exact same hours worked.I don't know exact pay but I do know that some full time cast members in attractions that had been there for 20 years were making more than the young managers in our area. I found it a little odd.
I remember of a few hourly CM's in my area earning over $40k/yr 8 years ago, when starting management pay was just over $31k.
