Well it certainly won't be all in one sitting, I can guarantee you that. No, it will be a gradual process over the next handful of months:
I'll start with Episode I (because screw all y'all, I like that movie), followed by the 2003 Clone Wars, the 2008 Clone Wars (or at least the episodes I like), Rebels, and top it all off with Episodes IV, V and VI (Despecialized Editions, of course) at the very end. Gotta save the best for last after all, and it has the added bonus of segwaying into The Force Awakens quite nicely. Episodes II and III will not be viewed. They are not part of "my" Star Wars canon (except the Jango Fett bits, I may cherry-pick some of those scenes).
Interspersed between all of it will be sessions playing games like Tie Fighter and Jedi Outcast, as well as readings of books like the X-Wing novels, the Thrawn trilogy, and Brian Daley's Han Solo adventures. A chance to take a walk down memory lane and acknowledge the better parts of the "Legends" continuity before the new one really starts changing things up.[footnote]Not that I'm opposed to the new canon. Quite the opposite in fact, given how the old one became a hopeless, convoluted clusterfuck of questionable quality.[/footnote]
