I understand the concept that you can use your pass for ten days (the clue is in the name '10 day pass', right? ), and I think those ten days can be within a twenty day period - is that right? I also gather that there is unlimited access to the four main Disney parks, unlimted access to the water parks and all the other 'extra' bits. What I'm not sure about is whether you can use 10 days at the main parks <b>and </b>10 days at the water parks ( a bit like the hopper pass Plus Features), or whether once you've ticked off a day it's just 10 days, regardless of where it's used (I suspect it is this). Does that make sense? Can anyone clarify that for me, please?
