Where to smash

Scenario:

My bf and I go to a private university, hence, there's no chance of getting some or doing anything. Parents have me on FindFriends app on iPhone. They're dropping me off on the 20th Saturday. My bf and I want to have our own time since we never have any on campus cause the rules and curfew suck. I know, I hate the rules and everything too. Idk why I'm going. He got a hotel for one night so when my parents leave, we can just go have our time alone. But my mom just told me to instal a tracking or finder app on my phone. Should I leave my phone in my dorm for the night and take my Mac so if she texts or calls I can respond by that?
