A:
Working in hotels that sell alcohol is Haram, as it is cooperating in sin and transgression. Allah (Exalted be He) says (what means):
Help you one another in Al-Birr and At-Taqwâ (virtue, righteousness and piety); but do not help one another in sin and transgression. And fear Allâh. Verily, Allâh is Severe in punishment.
Accordingly, the income acquired from working in this hotel is Haram. As to what you mentioned about depending on this money to provide food and drink and raise your children, it is obligatory on you to make sincere Tawbah for the past and to dispose of the remaining money as Sadaqah (voluntary charity). Your husband also must stop working in this hotel and look for a Halal way to earn a living. Allah (Exalted be He) says:
And whosoever fears Allâh and keeps his duty to Him, He will make a way for him to get out (from every difficulty).
And He will provide him from (sources) he never could imagine. And whosoever puts his trust in Allâh, then He will suffice him.
