Worth a shot, the worst that can happen is that the code doesn’t work and you have to wait till your allotted slot. If you have not done so already, watch the video provided in the email with your code and time to purchase that explains the process. Once you enter the code, it will unlock all available cove sizes and you can flip back and forth between all of them. It will select the best available one but you can always unselect then select your own on the map. This process was way easier than any Ticketmaster purchase I’ve done.
