Sorry if I'm posting in wrong forum. We have a 5 year old where we would probably be going to WDW in the summer months, but would like to take a trip the first week of December every few years, probably not every year. I've watched The DVC Show\DIS Unplugged (actually watched The DVC Show latest episode today about rookie mistakes and still confused on use year). I understand the concept that it is different from when you can make reservations and that use year mainly has to do with banking dates if I understand it correctly, but I'm still confused on what would be the best use year for us in that type of scenario especially with the holding of points if a trip is cancelled, etc.
My guess might be that there would be more flexibility in rescheduling trips later on when it's not tied to your daughters school schedule? But thinking of your comment about heat I think I might lean towards the December UY as it still covers banking for trips for Dec-July or really August. An April UY works for travel with your daughter too but you'd lose the banking window insurance later where the December UY covers a lot of it. Just the direction I believe I'd lean. And it would only come into any importance in the case you ever had a last minute cancellation.
