I did this with my wife last February and as a solo traveller this past August. Both times were awesome. My wife and I had dining reservations at Mama Melrose (RIP) at 7:10 and we enjoyed Fantasmic @ 9:30. We had plenty of time later to do everything we wanted to do, including RRC, TOT, Slinky Dog, ROR, and MMRR. We spent plenty of our time in Muppet Courtyard getting pictures and enjoying the quiet. In August as a solo I got to the park right at 6:30 and was let in at 6:50. Again, enjoyed everything and took my time walking around and enjoying the ambience of HS. It was warm, so I didn't run from attraction to attraction, but I would say both experiences were well worth it. Other than MK after hours, HS is our next favorite!
