I dunno if this is what you're suggesting, maybe I'm misreading, but you kinda make it sound like there wasn't much interest... There was a huge queue all the time, it's not like there were any quiet bits where no one was going in. The only way there could've been more than 250k was to extend the lying-in-state period or to make everyone run round it. (Which does make you wonder how they got to a 1m estimate).
