How to solve the problem of three women and two men going out to travel and stay?

It's a bit unrealistic to add an extra bed ... If possible, couples can live in a big bed room, and then open a small bed room for the remaining men, two girls' bid opening rooms (two single beds), if not, two men's bid opening rooms and three rooms. Home Inn has such a big bed, which is a national chain and the service is very good. The price of one room is close to 100-200.
