We also just returned on Saturday after spending a week there.
We noticed this too. At first we thought it was due to extra magic hours for Disney on property guests. You could walk the parks and most things were open like food and souvenir kiosks, but there was a rope just past Norway in Epcot until the park officially opened. You could also get in line for rides before the park opened.
I would like to add if you're hoping to be immersed in the Season of the Force, you might be disappointed. It was canceled, per a cast member at Magic Kingdom. However, you can meet Darth Vader and Chewbacca at Hollywood Studios (we did and it was fun!). There are also two gift shops and a few stands to get a BB-8 cup or Darth Vader popcorn bucket.
