We are trying to pick out what restaurants we want to get reservations for and are trying to decide on which days for each park (we don’t have hoppers). We are going August 19-29th 2017 and are about 7 months out. How likely are the park hours and EMH likely to change? That is what we are basing most of our days on is the EMH. But if they change they can potentially mess up our reservations.
