Is it forbidden for two sisters to stay at their friend's house in the countryside, with the girl's family present?

It is permissible for two sisters to stay overnight at their friend's house without a mahram (unmarriageable kin) present, provided that it is not a journey unless a mahram is present, and with the permission of their guardian. This is also contingent on their adherence to the Islamic hijab, avoiding impermissible mixing or private seclusion with non-mahram men, and ensuring that their stay does not harm their honor and reputation.
