We'll be at AK for at least 3 full days and nights on our next trip, but we'll be there for 14 nights with 10 day park hoppers, so we may hop over there on other days, possibly if we get bored at Hollywood Studios which happens quite a bit, usually after we ride ToT and RnR each several times and Star Tours 1 or 2 times. Animal Kingdom was our favorite park even before Pandora, so we're really excited to be there now, but we love the rest of AK at night as well, which is why we're doing 3+ days and nights.
