I bought 5 day hopper passes with 2 plus features. Does this mean I could go to major parks for 5 days then the 2 other parks for the other 2 days, totalling a 7 day trip? Or do the plusses have to be used on one of the days I go to a major park. If I don't use the whole hopper, do I need to save one regular day to be able to use the plus features later? Hope I haven't confused everyone!
