My strategy is sort of the opposite; I am loading up as many points as I can in the first round now, even if it uses all my cocoa (I still have plenty anyway). Points are never easier to get than the first round: points earned don't increase each chapter, but getting full-point challenges can be more difficult in the next two chapters (for example, non-level-10 Merlin is one of the challengers in round 3, and I think the number of cocoas per character per challenge increases each chapter). And completing each chapter is insignificant to me; the Aladdin chest, Soul chest, attraction enhancement chests, and leaderboard rewards are not anything I need or care about. All I ultimately care about is getting the 75,000 points for happiness, and I should have that mid-chapter 2. I'll probably keep going to 100,000 for the worthless costume, which I will also get prior to the end of chapter 2, but then I can have the option to pretty much check out of the event completely for chapter 3, just coming in for daily and weekly tasks. So how much cocoa I have later in the event just doesn't really matter to me, so I'm just using it and sending out full challenges as quick and often as I can now. And even playing all the way through prior events in this manner, I always end up with plenty of cocoa left regardless.
