Two-a-day or single your call.
Start with a chipper, good enough for royalty. Word has it they've tried it at the Palace already. Should take you no more than 15 minutes-ish.
You'll start warming up as soon as you want but the start times will be as individuals, as you get ready.
Those who are planning on taking a run at the Aluminum Man can try a second (or single) WOD this afternoon. Known as the "Cardboard Man" it's a short but nasty version of the A.M. The start time will be @2:00 pm and the distances/location will be on the board. It's also a great warm up for the "Sprint Tri" WOD that will be held in July.
