It can be cheap if you are in the US. However, for Asia folks, it is not that cheap considering it is all overseas travel. In addition, all-in-one event like the current summit makes us much easier to get the travel fund from the company, since the company only need to send everyone (tech, ops, business, strategy) to one event. Even as an ops or developers, doing presentation or a meeting with one or two important company can be very good excuse to get the travel money.
