What I have seen happen most often in these situations, because most definitely the language barrier can cause concerns, is that a lineup is arranged for the gentlemen that come together. The hostess lets the girls know in advance that one gentleman is going to accompany the others to translate. If more than one gentleman is choosing a lady from the lineup, all the gentlemen choose their ladies and then the lady chosen first will take her suitor and the translator to her room and the other ladies will wait in the bar with their gentlemen until the negotiation is complete with the first lady. The first lady will escort the translator back to the bar, he grabs the next in line and they head to her room to negotiate their play.
A second girl is only required to accompany the gentlemen if there is playtime involved. For translation purposes only, the two men can go with only one lady to her room.
