Have to decide if its worth it for me to spend 1500+ bucks to attend Twitter's Open House in SFO or 650 bucks(Opp Cost) to attend their NYC event..... if only it was scheduled on Fridays as opposed to Tuesday.

SFO
Pro:
On Tuesday which means I can arrive Friday night and walk around the city for the weekend
HQ(Maybe.. just maybe can meet CEO/COO?)
Con
Miss two days of pay/work(During the period my project is being implemented).
Gonna be showing up to work with Wednesday with zero sleep.

NYC
Pro
Only miss half of day of work.
Con
Not HQ, six hour trip only. Or stay in NYC for the night then take the 6AM flight back to YTZ
If my arrival flight is delayed even by one hour I am literally screwed. And knowing AC's track record..
Regardless which ever city I end up going... probably the craziest thing I have done yet. Aside from the time I flew to NYC for HTC's ONE M8 reveal. (Got a free phone that was higher than my plane ticket so its worth lol)

Any advice? Or thoughts on which one seems like a better choice. Or just neither?
