No, you can only join the virtual queue for Guardians of the Galaxy: Cosmic Rewind once per day during standard operating hours. Disney's current policy states that guests may only hold one boarding group for a specific attraction at a time, and once you have redeemed that boarding pass, you cannot join the virtual queue again at a later drop time (e.g., if you join at 7:00 AM, you cannot join again at 1:00 PM). However, there is a special exception for guests staying at Disney Deluxe Resorts, Deluxe Villa Resorts, or other select hotels on nights when Extended Evening Theme Park Hours are offered at EPCOT. On these specific dates, eligible guests can join a third virtual queue drop at 6:00 PM. This is a separate opportunity that allows qualifying guests to potentially ride a second time in one day if they were also successful in snagging a spot during the 7:00 AM or 1:00 PM distributions. For everyone else, once your boarding group is called and you have scanned into the attraction, your opportunity for the virtual queue is finished for the day, though you can still purchase an individual Lightning Lane Entry to ride again if availability permits.
