How much ,, playing ice skating???

Help! Where would you advise to sit for a good view at a Mandopop concert in Taipei Arena? For a good view of the singer. E.g. I don't mind spending the money to sit in the 2 zones right in front of the stage as it's a singer I really like. But the seating is all flat i.e. no elevation of seats in this zone. Is it worth spending the money cos will the view be blocked? Thanks so much!

台北小巨蛋にコンサートなどで行ったことがある方にお尋ねします。 チケットをコンビニではなく、会場の窓口で受け取る場合の営業時間をご存知ないでしょうか。HPで調べてみましたがわかりませんでした。よろしくお願いします。
