When originally announced In Oct 2015, Disney said the passes would exclude two weeks around Christmas and "the spring break" weeks. At the same time, it released the actual dates for 2016 which showed that the excluded spring break weeks were the Easter weeks. The assumption is that will be the same in the future. Note that both Florida residents and
DVC members can purchase the Gold pass. There is an even lowered priced Silver pass that Florida residents can purchase that excludes the Christmas and Easter weeks and the mid-June to mid-August summer period, which indicates Disney does not consider the non-Easter spring break weeks to be something that need to be excluded in that even lower cost pass, but you should assume that definitely the Easter weeks will be excluded from the Gold.
