Holiday Plans is the 4th episode in the series.
Every year the Bryces and Howard and Hilda go to the Glockenspiel in Bavaria but this year Paul is offering the use of a friend's villa in Spain. Typically Martin is appalled at the change of plan but calms down and asks Ann what she wants to do. She suggests the Greek islands and he actually goes with the idea. This also allows him to get one over on Paul when the villa turns out to be unavailable and Howard and Hilda end up at the Glockenspiel.
