Very good value for money and if you plan your visits beforehand, using the useful guide and map provided, you can save yourself a lot of hassle getting around and in locating the museums/attractions you want to visit. Only problem we had was that the 'hop on hop off' bus company we used only picked up every 45 minutes and on one occasion kept us wating 1hour 15mins! Also, bus stops had no identification markers displaying our tour operator, so we had to make sure we knew, when hopping off the bus, where to go to pick it up again for hopping back on again later.
