Quick Question: Does a filibuster require that every member of the party that is filibustering , or even, every Senator from either party, be in attendance for the entire duration?

If not, then that would mean the Repubes (ha, I saw someone else here refer to them as repubes and I thought it was the most ingenious thing ever) could just take turns so that the majority could go home and spend a comfy Christmas break with there families, and only a handful would have to stay on during Christmas day.
