Hey Howdy Hey Ashley and welcome to planDisney!
When in EPCOT, I always make time to see the Guardians and save the galaxy.
Guardians of the Galaxy: Cosmic Rewind is super fun and thrilling and is my favorite ride in all of Walt Disney World. As you mentioned Ashley, there are some specifics when experiencing the attraction. Let's review the details.
Just like you said,
Virtual Queues are available for this attraction at 7:00 AM from anywhere and again at 1:00 PM for those that are in EPCOT. Once you can join the Virtual Queue and secure your boarding group, you are free to roam the park or elsewhere until your boarding group is called. You should not have a problem park-hopping to another park and then heading back when it's time to ride. Just remember, once your group is called, you typically have about an hour to return for your ride experience.
Since you are an Annual Passholder, the Virtual Queue option is only available for select attractions. At this time, TRON Lightcycle / Run and
Tiana's Bayou Adventure in Magic Kingdom are the only other attractions that utilize this option. If you haven't gotten to ride Tiana's yet, I would highly recommend it! This attraction is amazing and it is super fun going down with Bayou with Tiana, Ray and so many new friends. You can't help to sing along throughout the ride!
I hope you have a Magical time on your next visit to the parks. If you have any other questions let us know, we are always happy to help!
To Infinity and Beyond,
Nick
