That is pretty expensive, I might pay $75 for one day, if the food was good, but it is unlikely to be much more than the regular vendors. I certainly am not going to pay $150 for a weekend day, but if they are going to have the jet noise on Sat. I probably will leave by then anyway, though I usually like to do some shopping at the vendor buildings then.
It seems to me that this is a small building in a large place, and like going to a fine restaurant, if you don't want to pay for the bottle of Dom Perignon on the menu, just don't order it, have beer or water instead. It doesn't affect my week if some people do pay extra to have this tent.And someone who spends most of their time inside the building is going to miss a lot of fun things anyway.
EAA is not Cuba where most everyone is equal in that they are all on the bottom.
