I have a resort reservation for early May. I am more than likely going to purchase annual passes, as we are likely to go a couple more times this year. There is a possible health situation that might make it necessary to move the resort date further out. If I buy the passes, and go ahead with park reservations, if we have to move the vacation, will the start date not start until we physically walk into the park, correct? That is, if I have to move from May to August (for instance) the start date will not be activated until first use? I would, of course, cancel any park reservations should it be necessary to cancel. Just trying to wrap my brain around this. I have had annual passes in the past, but that was well before the park reservation thing.
