New details on the Neon Museum’s planned relocation to the Arts District show museum operators are not only focused on the sign collection ­— they want to pack up and move the historic lobby building, too.

Museum operators will ask the Centennial Commission for a roughly $2.1 million grant for the costs associated with relocating the La Concha Motel lobby, a hotel building built in the early days of the Strip that now acts as the museum’s lobby at 770 Las Vegas Boulevard North.
