Glad you got those memberships, you might of been ok without them, but at least you've got the guaranteed tickets now. Hope you both have a great night.
What I would add, is if your goal is to follow right through to the final "IF" we were to get through you would almost certainly need membership for the following round(s). With that said it might be worth pre-empting and getting the membership now, which in theory would pretty much guarantee...
