The problem exists. It's not a question of avoiding a problem. It's a question of leaving the door open or having it shut.

Suppose he calls now and is told the cancelation policy does not allow him to get a refund, but the hotel is willing to either refund his money now, because of the confusion, or allow him to keep the reservation under the rules as intended. He then loses his defense if he wants to cancel his reservation. No Centre County judge (and yes, that's the state where I practiced law and yes, I grew up over the mountain from PSU) is going to allow him a refund, if it came to that, because he could have mitigated his damages when the policy was explained. One would be more likely to get a verdict against Disney in Orlando than a verdict against a hotel enforcing hotel weekend rates.
