A buddy of mine just texted me and he said he was able to get 6 tickets in 212 within the last hour He had 2 vouchers and he got 4 with 1 and 2 with the other voucher.
So it is possible to get 4 together. It's just TM archaic website that screwed everyone over.
Just a heads up to anybody. If you already got 2 seats with a voucher, you can still use the voucher to get 2 more.
