We enjoyed our visit here, as the museum is so well managed with very informative and interesting displays.
The only thing that made us confused was actually Traveloka's booking detail, as it was written that we need to contact the museum to confirm our visit. We actually tried to contact the museum and just got the reply after we visited. We actually managed to visit without any issues as long as we came on the date as written on the booking, visit the foreign tourist booth and asked the staff to scan our QR code. At first the staff seemed a little bit unsure as if they weren't familiar with Traveloka's logo, but thankfully it went well because the QR code could be scanned.
