I am planning a trip to Vilamoura for early September and I am interested in things to do, restaurants, driving and the weather. I'm told that this should be the end of the hot season but not quite the rainy season. I will be staying at the Hilton and I read that it is verye expensive to eat at the hotel. What side of the road do you drive on? I have traveled in other countries but if the roads are not labeled it might be challenging. Can I use my GPS there? Any advice would be most appreciated.
