I'd imagine that you would be refunded what you paid for the 1-day ticket (not 100% on that). However, as hotel stays are not covered by an annual pass, you would not receive a refund for the hotel stay. If the second day at the park is free, you would not be given anything for that.
It's worth noting that this refund is only available if you purchase the passes on the day of your visit and will not be given prior to or after this.
I'm sure if you contacted
the resort, they'd be happy to provide more reliable information.
Hope I helped!
