I originally booked the week after Thanksgiving with a 40% pin code. The pin code had an expiration date of late March for booking. I need to change to the week before Thanksgiving. The dates in question are covered on the brochure for the original 40% pin code dates. Has anyone been successful in changing dates with a pin code even after the expiration date for booking??? I'm not changing the resort or downgrading, just want to change dates.
