Well, I for myself didn't go on an off-road tour but a friend of mine hired a 4x4 and was glad that they had it. He did a rainforest tour in the southern part of the island and particularly after rain, the streets were a bit muddy. To go just on normal streets and side roads should be no problem with standard vehicle.
