Ok so stop me if this is a stupid question but what constitutues selling. If I have a $600 (thats total not per night) reservation and I give it to someone and ask them to pay the $600 is that selling? If so why not just cancel the room with the hotel (before June) as per policy. I'm not trying to scalp here but are people really just giving away $600 worth of hotel to strangers.
If you have PREPAID that reservation you may ask them for that amount. If not, you cannot sell it, but you are transferring it to someone else, and your credit card is being removed.
