It depends on what you want to eat. There is a Pizza Hut Express in the little grocery and there is Frankie Farrell's and then the pool bar had a decent menu some days. I just walked to all of these when staying there.
So, if you are basically only hanging out at the resort and not going places every day, then you could find some places to eat without going far. If you plan to travel to other places each day, you might want to consider a rental car.
