Go and have the barbeque lunch at Viklari, overlooking Lara Bay. The view is just sensational and the food is simple but extremely good as well as inexpensive (30 quid for 4, including booze!).
You'll need a car - some say a 4 by 4 although the track is good enough for a saloon car. You can walk off a few pounds after lunch by driving the short distance to the Avakas gorge
Go and see Kourion (or Curium if you wish) but don't miss the Temple of Aphrodite on the way or the Stadium.
If you get the chance get over to Y & P's fish taverna at Latsi - arguably the best fish taverna on the island (if you go on a sunday for lunch you'll find it packed with locals from as far afield as Nicosia, which speaks volumes for the food).
Go and visit some of the local wineries around Pafos, so when you are home later on, drinking this years vintage, you can say you knew the grapes personally!! (I like this one).
Buy some spices in Pafos market but have a freshly squeezed orange juice while you're there.
Other than that, lounge around the pool and chill out (grin) And enjoy!!
