Can I tag onto this? We have 3-day tickets but want to wait until we arrive to decide whether to go to the park that first arrival day (which would mean four days in the parks). Is there any particular way we need to go about doing this? Our scenario is this: if its gorgeous out (pool weather) and/or our arrival is delayed somehow we will stick with our 3 days and hang out at AKL our first day; if we arrive on time and the weather is too cold for the pool, we want to go to AK when we arrive (flight lands at 9:30 so ll:00?).
