Question is: how long is "a session"? When I was younger (way younger...) a session could be something from like 5 hours (saturday afternoon sessions) up to like 10 hours (saturday to sunday all-nighters, my favorites). These days, it's mostly 3 to 4 hour sessions. Anyway let's not weep on good days long past, my answer would be "At least five" based on current timeboxing (3 to 4 hours).

Oh I feel you. Today a session seems to be around 3 to 4 hours indeed. For most parties at least.
