You do not need to be on Walt Disney World property to secure a spot in the 7:00 Virtual Queue for Guardians of the Galaxy: Cosmic Rewind. I’ve done it from home! If it is the 1:00 Virtual Queue that you are trying for, you need to have scanned into Epcot. If you haven’t entered the park, the system won’t allow you to join. Make sure you try. Guardians of the Galaxy: Cosmic Rewind is worth the stress.
Here are Parts Two, Three, Four, Five, Six, and Seven of this series.
