I believe that I read somewhere here that the TIW is good for 13 months. Is this true? I ask because we are travelling to WDW on the first week of May (actually arriving April 30) 2015 and then again in the third week of June 2016. I want to make sure that if I buy the TIW card on May 1 that it will still be valid on June 30 of the next year. Does this sound right?
