That's actually not as difficult as you might think. Think of the sponsors you could get if you could gaurantee a certain amount of people going to the convention. And, besides that, imagine the price of a ticket if the companies put one together! Now, I didn't go to the original, but I'm pretty sure it wasn't cheap. If everyone were willing to donate a certain amount to site rental and the cost to take care of all the guests invited (Muppeteers, writers, directors, builders, etc.), you might find it would actually cost less than MuppetFest 1. After all, we're not expecting to make a profit off of it the way I'm sure the original did.
