I've been here 3 times now, and it is still pretty interesting. It's a small place, and I can't…read moreremember how much they charge during the tourist season, but it's interesting, and they have all the information for the displays in multiple languages (just ask the front desk when you walk in). Depending on your level of interest, you could spend at least 45 minutes in this museum just looking around and watching the 10 minute (or 15 min) video they have - which is also offered in English and German.
