How do I convince my parents to let me do this? My 3 friends and I (all 17 year old girls) want to rent a cabin and stay in it overnight together. 

I asked my dad and he said he didn’t know, and I asked my mom and she gave a flat out no. I talked to my mom a little more about it, and she became a little more open to it. 

I asked my mom why I couldn’t go and she said it was because teenagers can’t be left alone without a parent. I then told her that I was moving away to college in a year. She then brought up how there will probably be alcohol, which I denied (even though we will probably smoke and drink). And then she brought up how boys might come, and I totally denied it by saying that it was a girl night (there really won’t be any boys). 

How do I get them so side with me? We are all planning on doing it for a little Christmas present for ourselves
