Replying to Timberline Summer Pass Options

Some friends and I are planning to head out to Hood this upcoming summer. I'm aware of how expensive a trip like this will be, so i'm trying to figure out what the cheapest type of pass would be. We'll leave in early June. Does anyone know if they offer a June only pass or something? I know they have a spring one for around $100 but we'll be there too late for that. I would like to avoid buying a day ticket for 2 weeks straight if thats possible. If anyone that's gone to Hood in the past could help me out here, that'd be dope. Thanks!
