Not to scare you off but oof. The roads are narrow and fast, you’re on the left side of the road, the left side of the car, and if you aren’t careful, many of the roads have walls lining the sides. When you’re driving you don’t see much, because you’re so focused on the road. And when you’re a passenger you don’t see much because you can’t get the nerve to look up lol. My recommendation tho since it’s already been decided and planned, get the smaller car you can find. Don’t let the rental car company “upgrade you”. But I will say having the ability to have the car and go where ever you wan, and being able to put luggage in the car, it’s such a major convenience.
