I have visited this museum several times. Recently, they have made some improvements that took the well intentioned but well worn facility and exhibits up a notch.
The builder's exhibit, village area and new entry separate from the library were big improvements, in terms of freshened exhibits that the children enjoyed, and providing a separate entry to separate the library patrons from families accessing the museum.
I really hope the Lied Discovery Children's Museum keeps improving its exhibits and facilities so it ultimately becomes a world class facility. This museum is a great asset to Las Vegas.
