this isn't a discount, but it is a justification i thought i'd share. i was a little shocked at how much we were spending to stay on-site (we got the stay more save more discount, but with only a four night stay we are still paying $253/night at PBH) but then i came up with my awesome justification--for the two of us to buy universal express pass, it would be $180/day. so really, we're only paying $73/night to stay there--and i can deal with that!
hope that helps! have a great trip!
