Advice on Candlelight Processional

[dspads]

I would like to see the CLP when we are in WDW in 2 weeks. Of the following nights, which would pick if your biggest concern was wait time? What time is best and how long before do I need to arrive?

Sat 12/1 - Whoopi
Sun 12/2 - Andy Garcia
Thurs 12/6 Blair Underwood

TIA!
