Someone else may have a better answer to this, but the way I understand it, you have 5 days in the 4 major parks and 4 visits to either Pleasure Island, Typhoon Lagoon, Blizzard Beach, or Wide World of Sports. The 4 Plus visits are counted as a visit each time you go to one of the parks just listed. In other words, you may not park hop between these parks with this pass. It is possible to get 9 days worth of visits to the parks if they are used wisely; for example use each of the plusses for a whole day in one of the water parks and spend the other 5 days in the major parks. I think tickets to Pleasure Island (if you chose to visit there) can be bought very cheaply at Ticketmania via the mousesavers newsletter. I think for the value, they are better used for water park visits. Can someone help me with this or correct me where I'm wrong?
