Doraemon: Nobita to Buriki no Meikyuu

A man watches a late-night TV ad for a luxurious resort and, half-asleep, books a stay without realizing he's interacting with the commercial. The next day, he shares the plans with his family, only to discover the resort doesn't appear on any maps. A suitcase later appears in a child's room, containing a portal to a resort operated by tin robots, with no cost involved. However, the invitation appears to have an underlying motive.
