This so-called museum is seriously overpriced for foreigners, terribly maintained and managed.
As a foreigner, you're charged 100k for entrance, but the place is smaller than a football field, with three poorly presented small exhibitions. Many of the exhibits are missing and exhibition boards in shambles. They charge foreigners so much money, yet the English introductions are barely readable.
This museum is part of a larger temple complex. You can visit the other part, but as many temples in Indonesia, you need to pay for a sarong and haggle with the guy at the door. This can be quite annoying and a deal breaker for many people. So I reckon just don't go, you don't have to go there in order to see good temples buildings.
The place has two entrances, one for tourists, the other for staff. But the one for staff is not guarded at all, which means anyone can just waltz right in and enter the museum grounds without paying!
All in all, not recommended at all, and you won't be missing much either.
