We have never been to the Natural Pool and don't feel deprived. Just get in it and drive. Last January we had a 4 x 4 for one day to drive around the island and were glad we did. December and the time just prior to our arrival had been extremely rainy, so needless to say, we got stuck. That was until he realized I used to go 4 wheeling with my guy friends when I was MUCH younger.
Roads signs are terrible.
Aruba does many things well, but road signs are not one of them. Also, the Aruban people are extremely friendly, but their driving also leaves a lot to be desired. Aruba is a foreign country thus has international road signs and they do many things well, but road signs are not one of them. That was my last vacation in a car All in all, like I said, you do not have to rent a car unless you plan on doing A LOT of touring. If you do rent make sure you have insurance on it.
