Is it possible to get the train tickets to Beijing at the Tianjin railway station during the Chinese New Year season?

ETA Tianjin on 13/2/2011 at 2:35 p.m. Plan to take shuttle bus to Tianjin Railway Station and then take bullet train to Beijing. As it is the Chinese New Year season, would like to find out if it will be possible to get the train tickets on the spot? If not, what other alternatives are available to get to Beijing?

As the bullet train will be taking us to the Beijing South Railway station, how do I get from the Beijing South Railway station to Lu Song Yuan Hotel at No.22, Banchang Lane, Kuanjie, Beijing?
