I would assume Varsity wants to fill up every available venue at Disney that weekend with teams. (Disney wants this also.). They also want to encourage teams to keep chasing bids as long as they can at Varsity events and keep it just "exclusive" enough to fill up every time slot. While I intensely dislike the impact the event has had on the industry (extended season, vastly increased cost, incredible damage to independent EPs, etc) it has been an absolutely brilliant business move to leverage their position in the market. I don't see them doing anything different while parents/athletes continue to put so much value on those bids.
