Welcome! To the Nobi Hotel / I Can Only Speak the Truth

The company president of the American office has brought forward his visit to Japan, and has brought his daughter, Maria, with him. Dad's supervisor has asked him to look after her by taking her to a luxury hotel, but they couldn't speak English, Doraemon gave Maria a translator so they could understand each other.

The Nobi's pass their house off as a hotel and try to make Maria's "stay" pleasant while using only two 3D Projectors, and the Nobita family pretends to be the owner of the hotel with Doraemon as the manager of Nobi hotel.
