Unusually for this series, this is an episode set in a foreign country but which features English dialogue. Evidently, Mickey and Minnie are tourists rather than residents in this one.
Minnie's ringtone on Mickey's phone is "Minnie's Yoo Hoo," which was Mickey's official theme song before the "Mickey Mouse Club March."
This is the first cartoon to take place in a foreign country (Monaco) where dialog is in English rather than another language besides it.
Limonade gazeuse is French for "soft lemonade."
