Hello everyone!

Need your input po. My family and I will be spending the holidays in Baguio (somewhere on Mission Drive). We'll be coming from Marilao, Bulacan. Some people we've spoken to, suggested we leave at 12 midnight or 2 AM.... to avoid traffic. I know it is too risky to travel at night, but we are traveling in a convoy of 3. Any tip on what's the shortest and safest route please? (I heard there is C2 hiway). I have Garmin installed on my phone, but don't want to rely on it too much (wish there was a latest map I could download somewhere). Any help would be greatly appreciated.
