The NDA MPs will also be joined by the lawmakers from the AIADMK, the TRS and the YSRCP, three regional parties supporting the candidature of M Venkaiah Naidu, the BJP sources said.
Naidu will also address them, seeking their votes, they said.
The dummy exercise will be followed by a dinner and Prime Minister Narendra Modi is expected to join the MPs then. He will also speak to them, the sources said.
Both Modi and Shah in their addresses to BJP members have emphasised on voting correctly to rule out any vote going invalid.

Unlike the presidential election in which the electoral college also includes MLAs, only MPs of the two Houses can vote in the vice-presidential poll.
Naidu, the NDA candidate, is all but certain to win the election in which the opposition parties have put up Gopalkrishna Gandhi as their nominee against the former BJP president and Union minister.
The electoral college comprises 790 members and parties with 484 members have already pledged their support to Naidu, who is also expected to be backed by several nominated members.
