No offense to Alex but Worlds isn’t so expensive that one would need a Kickstarter to go. Hotels VERY close to the event can be had at the FFG corporate rate for 60$/night. We attend in groups of four so that ends up being 15$/night. Food in Minnesota is also not expensive. it’s the Midwest. the cost of living is reasonable.
They usually announce the dates well enough in advance that even a flight wouldn’t be too expensive. I imagine no more than 300$ round trip if booked in advance. So if you ant to indulge in the food and drink a bit, it can easily be done for 450$ for all four days if you can find people to room with.
