Hiya Angela!
Welcome to planDisney, and thank you for sending us this groovy question! I am so excited that your magical trip is coming real soon and that you will be able to experience
Guardians of the Galaxy - Cosmic Rewind! This attraction quickly became one of my favourites at the Walt Disney World Resort, so it is definitely on my "must dos" list!
Although it is not necessary for each member of your group to download the
My Disney Experience mobile app, I recommend it as it is so helpful. When trying to get a boarding group, each member of your group can try at the same time, and whoever gets a boarding group first will automatically stop the others from getting one. Therefore, there is no harm in all trying at the same time. I usually do this with my friends too, and I've always been able to get a group! Just open your My Disney Experience mobile app early and keep an eye on the time.
If everyone in your party can also have their own
My Disney Experience account, I highly recommend they do so! Indeed, although it is important to plan out a Disney vacation, the mobile app also allows you to make last-minute changes to your itinerary or to experience new things. As someone who gets "hangry," I absolutely love the
Mobile Food and Beverage Ordering service, which allows me to order my meals in advance and skip the lines. Speaking of skipping the lines,
the mobile app also lets you purchase souvenirs at select merchandise locations, so you don't have to wait in line at the register. At busy times, this is especially helpful! Lastly, I always like to use the interactive map to check on wait times and find other things quickly, like character experiences, food locations, restrooms, and more. If your group ever needs to split up, the app is a great way to meet up at a specific location, as it even gives you directions to get to where you're going.
I hope this was helpful, Angela, and that you and your fellow guardians of the galaxy will have the best day ever on your upcoming Disney vacation. If you have any other questions in the time leading up to your trip, please don't hesitate to reach back out. It is always an honour to help fellow international Guests like me!
Have a magical day,
Ariane
