If you're staying for 6 nights, how many days would you buy park tickets for? Would you get 5 day passes and not do the parks on arrival day or departure day. Or would you get a 6 day pass and book it to one of the parks as soon as you get there? I'm thinking I would probably want to do that. We'll be staying at CR so we'll be so close to the MK. But, we don't have flights yet so don't know what time we'll get there. Hmmm, are these easily changeable, if I decide I want one less day?
