Krakow is well worth a visit and this is a great guide and mostly accurate. However, the Schindler factory tour is worth a visit - whilst the building facade is bland the interior is a really good walk through war time Krakow with quality exhibits..the guide needs an update on this. Castle is a must visit! Try to avoiod queuing to purchase castle tickets by going early / or at off-peak time.
Agree that the river cruises sold to castle visitors are a 'miss' - not really worth it as river frontages are not a feature here
Krkaow Balice airport - hint... don't go airside until necessary as there is ittle shopping or amenity there! landside has better amenities!
We did not follow any specific suggested day walks, but rather pot-shotted as a general guide. Book slips into a pocket easily and has an all important removable city centre map, essntial for initial bearings and directions when freshly arrived. As with all guides, this one is out of date before hitting the printers, some quoted free visits now being charged, but charging in Poland is not like admissions in the UK, you won't need a months wages! Some useful points of interest were followed and on balance the book was useful. Probably not as full of info as a 'Lonely Rough Planetry Guide' but they can be bulky and not so easily carried in these days of minimalist cabin luggage. Does the job for a city visit perhaps 3-5 days, worth carrying as it is unlikely to break the bank or your luggage allowance.
