Get the Glass Pass, well worth the money
The glass pass is an investment which definitely pays off, no matter how long you will stay in the region (and visit shops). It costs only 95 SEK (2009) and allows you free entrance to any of the glass factories, a 10% discount on any purchase above 500 SEK, plus discounts at many other shops, museums, accommodation, restaurants, activities (like blowing glass on your own) and for the famous hyttsill, which is a tradional evening meal with herring (sill = herring) in the factory. Have a look at Kingdom of Crystal’s website where you can download the offers as pdf. Take into account that the famous glass manufacturers will charge for a visit in their factories: Kosta, Boda, Åfors and Orrefors charge 30 SEK and Nybro charges 40 SEK without the pass. I was very grateful for the existence of this pass because it saved me approx. 1000 SEK, but then I was in the region for 3 days and drove all the way from home and back with a car to be able and buy loads to bring home (I would never have done this otherwise but would have flown and rented a car in Sweden only).
It might be a different story if you are coming as family with kids. Maybe. Just do some maths and you will know if the pass is a good idea for you. And consider that you will buy more than you originally planned to do, no matter if you come by car or by plane or train and have the goods shipped to your home. It is a law of nature, haha.
The Kingdom of Crystal’s website is a wealth of information. Here you can also download the 42 page (10 MB) brochure about the activities, the individual glass factories, the places to stay and eat and a map with the locations. This brochure is available in Swedish, German and English as download and in several other languages to order online. The website itself comes in ten different languages: Swedish, Finnish, English, German, French, Italian, Russian, Polish, Dutch and Japanese. Currency converter.
