(407) 828-1000
Sounds like a good JobLine question.
I know just enough to say, in general, that many cast members work just a day or two per week. Also, in many cases, schedules can be adapted around an individuals availability.
I also know there's a current need for entertainment cast.
So its a definate maybe.
But for particulars, you really ought to call that JobLine - (407) 828-1000. It isn't just recorded stuff - you have an option to speak with a rep. Or stop by the Casting Center some day.
