The first thing to do is to look at how far it is to your next charging stop. Typically, that's around 100 to 150 miles, but in New York it might be far less. Charge enough so you can comfortably get to the next Supercharger and don't worry about it.I am unfortunately in an urban situation without a home charger.
So my scenario is how to best get as much charge into the car at a local L2/L3 charger the day before a big trip.
