I think 1.5 stars is appropriate for the Bethlehem site, it is newly established this year and I enjoyed my visit but there is much to be desired, which I do think that they are working on. Give this site more funding and staffing and I believe it can be a great site, up to 3 stars. It's an extremely interesting history and they are working on restoring the destroyed buildings. It is not worth more than half a day in my opinion with the Museum and a short stroll visiting the buildings you can read every plaque in that time. The employees are all very passionate there and love the sites, it's clear there is a lot of care that just needs funding.
