We are planning a trip from Australia to WDW and want to make sure we choose the best time to go. We don't get to come often so we want to do it all whilst we're there. DH hates humidity but 2DS and 2DD really want to go to the waterparks. We'll probably spend a couple of days at waterparks but rest would be at theme parks. Our holidays fall in January or April. Which would be the best month to come?
