We own the basic game of Carcassonne, The River 1 and 11 and now the Inns and Cathedrals expansion. We have played a few times with this expansion and are just getting used to it as it really does change the game in that any uncompleted roads which have inns on them, score you nothing at the end of the game and also any uncompleted cities with the cathedral tiles in score you nothing at the end of the game. However, if you do complete these roads and cities you get double points for the roads and triple points for the cities. I would personally recommend you play the basic Carcassonne game until you are used to it, especially the scoring. Then start playing with the River expansion, the River 11 and then next this expansion. We would definitley recommned this expansion for those who want the basic Carcassone game to be more challenging. We find the game takes longer with the expansion not only because of the extra tiles of course but because there are more things to consider before laying a tile so demands more thinking time!
