The island is super easy to drive around. We like Irish, also rented our car from Daniel, super super nice man! The easiest way to explaine about the grocery store (Centrum), but there are many more, is this. Reguardless of where you are staying, everyone fly’s in to the island. So think of it like this, very simple, when you leave the airport, go right, continue down that road. You will run into the first round, there are three between the airport and Centrum. At the first round as with the rest, take the second turn off or road, as if the main road goes righ5 through the round. Continue that way until you reach a normal intersection with traffic lights. At this intersection turn right and you will see Centrum on the left. Most all roads lead to the same same place! And from there just continue on to your destination and you will always find the grocery store. Also most rental car agency’s have a GPS with all this info in it, super easy to use. Hope this has helped
