Most passholders DON'T spend money. They only visit for a few hours and not eat meals, buy souvenirs, etc. They go and ride a few rides and leave, eating meals outside the park. Those resort guests who they are targeting are just like the ones Disney targets, eating two or meals on property each day, buying all the souvenirs, playing the games, and riding the rides. Not just coming to ride a ride or see a concert.
I know there are time that passholders will buy a meal or a drink or a souvenir, but those are the exceptions rather than the rule.
I wouldn't be surprised to see a discount offered to passholders on tickets to VB, but no freebies. I'd guess you'll be able to get a ticket for $60 +/- with your AP.
