I think the vinyl sticks out more in BJ as it's a brighter house, so you're more prone to noticing that shiny vinyl if there's lights bouncing off of it (backlighting as well). Also, I know some people recently cast for BJ so there's help on the way there.
There's just no way they are filling to 100%. I know it's been two years, but there's no international visitors and the only time this event has ever reached capacity before was during hell week.
