We own where we want to stay. We usually book home resort 11 months out & know we'll be perfectly happy staying there. Then at 7 months if we want to stay at a different resort we'll switch if there's availability. We have also come to enjoy a split stay some trips. Our kids are old enough to pack themselves & willing to live more out of their suitcase to make it easy. We never have a car. Disney moves everything for use including whatever's in our fridge & we've never had a problem. Our stuff arrives COLD & in perfect condition. We even moved a specialty cake we hadn't finished & it arrived in perfect condition.
BWV at the weekend for SWW or Christmas time so we can walk there then move to VWL to spend more time at MK & because the boat ride is divine.
Any other resort & then last few days at AKV where we'll spend less time in the parks. We'll wind down by the pool, recover from the parks, enjoy the resort, & go home more relaxed.
