She didn't say that easyWDW said that HS is a 2 day park; she said it's recommended 2 days during the time she'll be there while EP is only recommended once. Personally, I think EP is a 2-day park, so I would do 2 days there. Also, although there may only be one day where EP is the most recommended park, I would bet there's another day where it's recommended, but not most recommended.
Yes there is another day that week it's recommended but it's the day we'd be going to
MNSSHP. And because of that we won't be going to EP and The party on the same day. I guess we'll just chance it and go to EP on that Friday even though it's technically not recommended. If it will help, here is what the week says on easywdw:
