I'm in China, and if I sign up for a digital lounge or lab, It's either me or Apple staying up all night. So, what's the case to activities for areas not in the same time zone as USA?
In the past, WWDC was in-person, so all of the labs were during the day. I can't say what will happen at WWDC this year. However, since the last WWDC, Apple has had many additional online support sessions at all hours and in all different languages.
And in any event, getting up at 2am is kind of a WWDC tradition, if you wanted to see the keynote in person.
