Great value, highly recommend it. Just so easy to enter museums, etc, and included public transport over a wide area. On our last day we paid for a boat trip to Vaxholm to visit the fortress and have a seafood meal on the waterfront and used the card to catch the bus back to Stockholm.
Bus left late (which meant we missed out later in the day from seeing inside a working windmill staff did not check PA system was working upstairs in the bus so we missed out on all the commentary for the trip out to the area.
Poorly guided and disorganised.
