I did my first one a few months ago. The business that I worked on didn't win, but I learned a lot from my teammates and the other teams that were there. For example there were several teams using wireframing or mockup tools to create simulated mobile apps as their MVPs, and I got to see what they could do with them. My teammates were able to learn from me how to build cost + revenue projections and "what if" analyses with a spreadsheet. Other folks on my team spent the weekend figuring out how to work on an idea with a 3D printer. I suppose if you don't have anything to learn, it might not be worth the time. But who doesn't have anything to learn? Also the food was good, the booze was unlimited, and I got a nice t-shirt out of the deal, so it's got that going for it.
