the "plus " features are for PI, the sports complex or either water park, not for DQ. you can use them on any day, in other words you can go to 7 days of the "big 4" parks and 4 more days to water parks or use them on the same days ie Mk during the day and Pi at night ( I think you might need a hand stamp but not sure about that)...personally, unless you want to go to PI, I think the most economical way is use them for the major parks 7 days and then the water prks the other 4 which is 11 total days of activity. We plan on interspersing the water park plus days with the other park days for a little break from the 4 parks and will probably have some pluses left to use another trip.
