Someone posted something on Insiders that I thought I'd post here as a heads-up/recommendation.
They wondered if the hotel would honor DOA cancels on reservations made in 2014 for 2015 stays. I said they should - but that it's a good idea to print out the confirmation email showing all the ressie details, including the cancel policy, and to make sure they have it with them in case or can fax it in case there's a problem.
Cheers.
