FWIW, we're intentionally going to MK on party days (lighter crowds) and going to the MHSSHP also, but we won't be doing rides during the party. We're going with our two young kids, so we're skipping park hoppers. They won't last that long anyway.
I wondered about that option. It would be less $ than hoppers. We're going with friends who've never been so we could devote the EMH to the shows, parade and fireworks.
