It could work. Maybe they have been working together the last semester or something on this project; the idea had to come from something and it's hard to coordinate that many people and find the place, etc. They might have some plans/funds too from somewhere. I would feel bad being left out of such an enterprise. One of my best friends from high school moved in with other girls in college (we went to the same college) and that made me feel a bit lonely/sad. It's hard for me to watch others do something I'm not able to at the moment for some reason.
