Hi, no there really isn't a way to check to see what is available before you commit. I would have to create an invite through our team clubhouse and then it's a roll of the dice as to what is left over at this point. Please let me know if your friend would be willing to take that chance. We really are at the last moment before our team will be disqualified, and that would be a shame considering how much training the team has done.
Thank you for the consideration!!
