Have an upcoming trip planned for 5 (all "Disney adults"), so tickets are expensive. We are DVC members staying on points so don't have a package. Depending on how Coronavirus progresses and the rules about return-to-work following travel by our employers, we may need to or want to skip the trip. I had never bought the "no expiration" option before but figured that would be worth it, however I don't see that as a possibility. Does anyone know how the date change option works--would I need to identify the new dates right away, and if so can they be changed again? Thanks in advance
