We've checked in on all different days. Last yr we checked in midweek to CR and went from garden view to tower magic kingdom view. This time we are checking in very late the day before Thanksgiving. Obviously there will be very little left when we arrive. Does that mean we have a better chance of getting an upgrade or whatever is leftover? I booked a tower room bay lake this time to make sure we are in the tower. By doing this, I know that this is the least room view/category I will end up with.
