AND, we decided not to use ours when we went in October so i sent an e-mail asking if they will expire. Mentioned that our daughter is getting married (GOOD GRIEF THAT'S THIS SATURDAY) and they might want to visit Harry for their honeymoon. I got a quick e-mail telling me that they will NEVER expire. I then received a phone call from the manager of customer care telling me the same thing and congratulating us on the upcoming nuptials (her word not mine) She then told me that if they decide to stay on-site to mention her name and a reference # she gave me for a "special treat"
