Should I go through with my plan?

I know it's wrong to go behind my parents back but I am 19 and attending college...my parents are extremely protective and I have a curfew or 11:30 on weekends and 10:30 on weekdays, my plan I'm asking about is this weekend my mother is coming to visit from out of town ( my parents are divorced & I live with my father and step-mother) ...I was thinking, since my parents pretty much hate each other had keep no contact what-so-ever, that I'd let my father/stepmother know that I was gonna spend the night with my mother and tell my mother that I'm going to sleep at home and will be back in the morning but instead go have a fun night out wit my bf and close friends...does that sound full proof?
