Firstly, make sure the car you pick for your Puerto Santo Tomas de Castilla adventure will fit all your passengers and your luggage. When you’ve done that, consider where you’re off to. If you’re going to spend the majority of your time in Puerto Barrios (which is just 2 miles away), go for a compact ride so you can squeeze into all the good parks easily. Is the open road calling you? Choose something with a little more room to move.
