A host made an offer to a friend of mine. After he didn't play because they had to leave due to a medical emergency the host said that the comp was "void" since he didn't play and he was charging my friend $2,000. I helped my friend and told him to call the VP or supervisor of the host and make sure to have all the emails the host had sent him. Sure enough the VP called an apologized and refunded everything. Make sure hosts live up to their word, and they cannot "revoke" a comp after they make you an offer.
