Another idea that just occurred to me, the android takes up so much time raising AI-IY she needs help with security and between her and Kali they create a Boston Lab style K9 unit to patrol the hotel. Then while the male character is on an extended vacation, his sister is getting married, the other girls get overly lustful and convince Kali and the android to add a dick to the K9.....
