Replying to How to convince rents to not make me go on vacation

I'm 18 if that matters or not. My parents are leaving today to go to Michigan for a whole week. We won't get back till the 30th of next week. I don't want to go, not because I don't want to see my family, I'd just much rather see them in Easter when I don't have shit to do.

My reasons:

1. I live in CO. Huge snow storm coming in so pow to ski all week.
2. I have the manager from Taco Bell calling me the 28th of next week, I'm supposed to start working the 29th. How am I supposed to do that if I don't get back till a day late?
3. Promised a bunch of people I'd chill with them.
4. Being Christmas season and all, the crime rates in our neighborhood have risen (seriously) so why not let me stay home and watch the house while they're out?

Any help on what to say to increase my chances of them letting me stay here?
