Wa `alaykum as-Salamu wa Rahmatullahi wa Barakatuh.

 

If your stay in the hotel provided for your father does not burden the company with extra payments, then you need not worry.

 

In case it costs extra for the company, then you should pay for it unless it is the standard practice of the company and there is a tacit understanding that the employees can accommodate their family as well with them.

 

If such is not the standard practice, then you should pay the company the extra amounts incurred by your stay. If they excuse it, then it is fine.

 

In the case of doubt, you should give the same amount to charity.

 

Almighty Allah knows best.
