They have a 2 hour parking limit but no one will really say anything to you if you're there longer from what I've seen. I'm there every morning and afternoon and will see people camping in their cars for days on end. Just need to note that I myself don't hang out there or anything. I just pass by and stop at it every day for my job down the road.
See if you can find a spot away from the sign. Then you can say you didn't see the sign. At Pilot, they don't really bother you anyway. Don't forget, that's not a truck stop. It's a Travel Center. When I travel highways, Pilot is my overnight place to sleep. Never had a problem.
