Are you sure thats why? Im pretty sure the reason it has a short line is because of a couple very vocal members on this board who have seen it several times hate it and it is therefore a terrible, cheap, cheesy, loathsome, and unimpressive attraction that is slated for demolition this year.
Believe it or not, it actually gets decent ratings from your average everyday guest. The concept definitely needs a fresh upgrade, but the attraction does a good job getting people off the streets for atleast 20-30 minutes
