In your payment options, should you only focus on the site in question or...

In thinking about mainstream price plans (non internet) I thought about Theme parks (Disney) and how they sell a ticket for one park up to 5 days, a Park hoppers and a premium pass to all parks. (Disney, MGM, Epcot, Animal Kingdom) various price points for each level.

Would it be too confusing to the surfer if this was an option with a full program?

Where the user could buy a day pass, a one month membership, a 3 month membership. Access to hop around 4 or 5 sites for a week, a premium membership with fill program (sites) access for a month?
