The vacation benefits sound decent too. Considering the probability of getting a similar Cravath scale offer in Singapore, if you are independent and can be away from home, I would say go for it, even if you intend to only be there for 2 years, and get NY called or English called while you are there. Your international exposure with this US (likely well known) firm will put you in good stead when it's time for you to come home, speaking from experience. Alternatively, you could also try to ask for a transfer back to Asia a few years later.
